GW16122 - Mini-PCIe Radio for Internet of Things - IoT

Software Disclaimer: This hardware was designed from a Texas Instruments Reference design. Thus, all software support is community supported through Texas Instruments.

Welcome

This wiki page is about the Gateworks ​GW16122 IoT Radio Card that is based off the TI CC1350 Reference design.

This enables ​Gateworks SBCs to act as a collector or gateway to other IoT sensors over the Sub-1GHz Radio band. This band allows for long range and low power communication without any carrier subscription required. No consortium or software subscriptions are required. TI has made all software open source and available.

Advantages of Gateworks IoT solution over SigFox, LoRa, Zigbee, etc:

  • Long Range
  • Create your own network
  • Do not rely on coverage of pre-existing networks (Verizon, AT&T, etc)
  • Open Source provided software by TI
  • No extra fees, subscription, etc
  • No joining of alliances/consortiums/etc
  • Works in remote areas where no coverage from other networks/carriers exist

Getting Started

It is beneficial to read this entire wiki page before getting started to gain knowledge about the product. Note that a majority of information required for an advanced IoT solution will come from TI.

Please follow the below steps to get started with the Gateworks hardware:

Hardware Requirements

All items purchased seperately

Software Requirements

Most software must be acquired from Ti because it is held behind a EULA.

You will need to download 2 software packages from TI on a Linux PC:

  1. TI SimpleLink SDK ​SIMPLELINK-CC13X0-SDK
  2. TI 15.4 Stack ​TI-15-4-STACK-GATEWAY-LINUX-SDK

There are 3 or more pieces of software:

  1. GW16122 firmware: pre-installed (so you can skip this step) is called the CoProcessor firmware
    • Download the SDK here: ​SIMPLELINK-CC13X0-SDK
      • Gateworks tested with SDK version 1.40.xx
    • There is a precompiled binary in the SDK here:
      • /usr/src/ti/simplelink_cc13x0_sdk_xxx/examples/rtos/CC1350_LAUNCHXL/ti154stack/hexfiles/coprocessor_cc13x0_lp.hex
    • Built from the source code here:
      • /usr/src/ti/simplelink_cc13x0_sdk_xxx/examples/rtos/CC1350_LAUNCHXL/ti154stack/coprocessor
  2. CC1350 LaunchPad Sensor Node Firmware
  3. Install Ubuntu 14.04 trusty-ventana (~210MB) on Gateworks SBC
    • Note Ubuntu Xenial 16.04 is not supported at this time
  4. The collector application running in Ubuntu on the Gateworks SBC
    • Must download Ti-15-4 Stack from Ti onto Linux Desktop ​http://www.ti.com/tool/download/TI-15-4-STACK-GATEWAY-LINUX-SDK
    • Once installed on desktop, find the file: ti154stack_linux_x64_2_04_00_19/prebuilt/bbb_prebuilt.tar.gz
    • Copy this file (bbb_prebuilt.tar.gz) onto the Gateworks SBC running Ubuntu either through wget or USB drive or scp or other options.
    • Extract this with the command on the Gateworks SBC: 
      tar xvf bbb_prebuilt.tar.gz
    • Keep note of where this was extracted for future reference.
    • Install the required packages for this application: 
      apt-get update
apt-get install -y build-essential nodejs

Getting Started Steps

  • Program CC1350 LaunchPad Sensor node as described in software section above
  • Connect GW16122 to Gateworks SBC in Mini-PCIe slot that supports USB
  • Connect antenna to GW16122
  • Gateworks SBC should have Ubuntu 14.04 Trusty installed as required in the software section above
  • Connect ethernet cable to Gateworks SBC on the same network as a PC/Laptop (for web gui viewing from PC)
  • Install the collector application software on the Gateworks SBC as described above in the software requirements section

Running the Collector Application

  • To start the collector application, run the script on the Gateworks command line: 
    ./run_demo.sh

The output will look something like below: 

root@ventana-trusty:~/ti-15.4/examples/linux/prebuilt# ./run_demo.sh 
Launching the Collector Application in the background
Found Mac Co-Processor Version info is:
Transport: 3
  Product: 1
    Major: 2
    Minor: 0
    Maint: 0
----------------------------------------
Start the gateway application
Collector Running as Process id: 1656
Launching Node-JS gateway application in background
Gateway is running as Process id: 1667

On your host, launch your browser using:
    http://192.168.21.136:1310
root@ventana-trusty:~/ti-15.4/examples/linux/prebuilt#
  • Observe the IP address printed out in the script output
  • From a computer on the same network as the Gateworks board, open a web browser and type in the IP address including the port and observe the web gui shown below:
    • * IMPORTANT Click the grey button in the WebGui on the left to open the network for new devices
  • Power on the sensor node that should then connect to the collector.
  • You can test the connection by clicking the 'Toggle LED' on the sensor node. This often takes 10 seconds to transmit and will affect LED D2 on the GW16122 if it is being used as a sensor.

Troubleshooting

  • Be sure any GW16122 boards have an antenna installed
  • Be sure the collector network is an open network so that the sensors can joined. By default, the network is closed and no sensors can join
  • Be sure that the Gateworks board and collector are all setup and turned on and the WebGUI is live with the run_demo script running on the Gateworks board. After this, then try re-programming the sensor firmware. This usually will force the sensor to re-join and search for new networks.
  • On the Gateworks board, you can try deleting the file in the extracted bin folder called nv-simulation.bin. This file will erase all previously connected sensor entries.

What's Next?

This example showcases a network setup between a sensor and collector, with the Gateworks SBC acting as a co-processor.

Future development will be accomplished through understanding all the Ti source code contained in the SimpleLink SDK and TI 15.4 Stack. Custom applications can be created using all of the TI provided software.

Please read and understand the following links below:

Additionally, reading through the rest of this wiki page will offer more notes from some of the research Gateworks performed.

Texas Instruments CC1350 Reference Design

For more information see the ​TI ​CC1350 Product Page.

RF Network / Infrastructure

The GW16122 / CC1350 operates on its own network. It does not rely on towers/networks installed by 3rd party companies (LoRa, Sigfox, Verizon, AT&T, etc). The entire network infrastructure is under control by the user. This includes sensors/nodes, collector(s), antennas and more.

Network Architecture

The default is a star-based topology system where there is one central collector (The GW16122 on a Gateworks SBC) that listens to all the sensors / nodes that are around it.

Sensor Limits

Number of connected users:

  • Support for 50 nodes in network is for the MAC-CoProcessor configuration, where the network employs full MAC level security (AES-128).

The Security table can take up all available RAM considering 500 bytes packets so some trade off are possible if the max packet size that must be supported by the application is smaller and the network size can go bigger (probably not reach 1K nodes). The network can scale up to much more nodes if for instance the security is removed at MAC level and deployed at application level (the code is hosted on Linux). The actual network size would be in that case more limited by the traffic profile (ie how frequently data is exchanged).

Range Testing

Gateworks did some basic range testing with the GW10124 2dBi Omni Antenna on the 915Mhz band. A successful link was acquired at 4500ft/1.4km over water.

Using a directional antenna, it is very likely the range could be increased further. Additionally, there is different modes and tuning that can be done in software to increase the range, such as LRM (long range mode).

TI has published an Excel spreadsheet for calculating theoretical distances. Please review this here: ​https://e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/t/375823

More range information may be found on the ​TI E2E Forums and on the TI documentation listed in the references on this page.

GW16122 Development

Much of the following information is taken from TI documentation which is licensed under ​​CC BY NC ND 4.0. This wiki page aims to get users up and runnning with the GW16122 by collating relevant information contained by aforementioned TI sources along with our own annotations.

The subsequent sections detail the information collected by Gateworks related to development with the GW16122. The GW16122 constitutes the following embedded systems:

  • TiVa TM4C1294NCPDT MCU - Primarily used to program the CC1350; converts USB signals to UART
  • CC1350 MCU - The main MCU responsible for taking sensor readings

A pre-made sensor node is provided by Texas Instruments:

​* ​Simplelink CC1350 SensorTag Bluetooth and Sub-1GHz Long Range Wireless Further information on the TI MCU's and tools utilized in GW16122 development can by found on the ​TI Wiki.

Developer Set Up

The following sections detail the steps necessary to set up a development environment for the GW16122. It is assumed that you already have a general understanding of Gateworks products and Linux based OS operations.

Development Tools

Development can be done on either a Windows or Linux x86 based machine (host). Various references to Mac OS exist for some tools but were untested by Gateworks. You will need to create a TI account through their ​registration page before downloading some of the software listed here. After creating an account you will still need to sign an agreement on each download indicating its intended use.

  1. JTAG USB dongle firmware for serial access and programming of Gateworks SBC (​Direct download link)
  2. Remote terminal program, e.g. ​PuTTY for serial connection to Gateworks SBC
  3. ​Code Composer Studio which is an IDE maintained by TI with preinstalled tools and libraries for software development on TI MCU's (​Direct download link)
    • Don't forget to run the post install script ccsv7/install_scripts/install_drivers.sh
    • The executable for the IDE is located at ccsv7/eclipse/ccstudio
  4. ​Simple Link CC13X0 SDK from TI's site is available on multiple platforms and contains prebuilt firmware images, example software, and documentation for working with the CC1350

Host Programming Software

Windows
  1. ​SmartRF Flash Programmer for quickly installing prebuilt firmware without code composer studio and especially useful for quickly programming sensor nodes using a GUI (Windows only)
Linux

​Uniflash Programmer which is a linux compatible alternative that includes both a GUI and command line interfaces

Some quick commands for installing Uniflash properly on an Ubuntu system: 

# Get the installer (software version subject to change)
wget --no-check-certificate http://software-dl.ti.com/ccs/esd/uniflash/uniflash_sl.4.2.1490.run
# Link udev library for installer error
sudo ln -sf /lib/x86_64-linux-gnu/libudev.so.1 /lib/x86_64-linux-gnu/libudev.so.0
# Run gui installer
chmod +x uniflash_*.run
./uniflash_*.run

Gateworks SBC Tools

The mechanism controlling the GW16122 will be a Gateworks SBC (testing was done with a GW5404-E.2). The Gateworks Ubuntu Trusty image is recommended and the instructions will use Ubuntu specific commands.

Some of the TI example projects make use of the Node.js framework in order to create a web interface to control what is referred to as the "collector" which in our case is the GW16122.

Once Ubuntu has been installed and a network connection has been established, complete the following steps to finish initial target configuration:

  1. Install necessary packages 
    # Always update your package manager information
apt-get update
apt-get upgrade
# Install packages for GW16122 development
apt-get install -y build-essential nodejs
  2. Acquire and install TI's 15.4 BLE stack source files from the ​SDK available online
    1. Since TI apparently only offers the SDK installer in the form of an x86 binary (ventana CPU is arm architecture), you will need to download the installer on a compatible linux machine, run it, and repackage the files for transfer 
      # ON SEPARATE x86 CPU LINUX MACHINE:
# enable execute permissions on binary downloaded from above link, your file name may be different
chmod +x ti15.4stack_linux_x64_2_02_00_03.run
# run the installer
./ti15.4stack_linux_x64_2_02_00_03.run
# package the install files from target directory
tar -czvf ti15-4.tar.gz ti/
    2. Transfer and extract the sdk files to your Gateworks SBC filesystem using your method of choice 
      # pull installation file from host pc (networked method)
wget http://remotehost/path/to/ti15-4.tar.gz
# extract the files
tar xzvf ./ti15-4.tar.gz

Software

A quick breakdown of the software running on each piece of hardware in an example network utilizing the GW16122:

  • Gateworks SBC
    • Ubuntu Trusty Gateworks Image
    • node-js (if using web interface)
    • serial program (if using serial api)
  • GW16122 Mini-PCIe Card
    • TiVa TM4C1294NCPDT MCU
      • boot_loader.bin - TI boot loader firmware
      • firmware.bin - XDS110 emulation firmware binary
    • CC1350 MCU
      • Co-Processor firmware (.out/.hex) - Either a prebuilt TI example or custom firmware designed with CCS

The following subsections detail the various software layers developed by TI for use with the CC1350 which is the main MCU in the GW16122 as well as Code Composer Studio and other general notes.

TI-RTOS RF driver

The RF core has a dedicated driver called the TI-RTOS RF driver, which is used for all interaction with the RF core. If you do not wish to use the EasyLink abstraction layer, there is also the option to do simple packet RX/TX using the TI-RTOS RF driver directly.

A reference for the example lab located in the TI resource center, see ​SimpleLink Academy lab Proprietary RF - Basic RX and TX.

For more information, see the ​CC13X0 Proprietary RF User's Guide.

EasyLink API

EasyLink is a simple abstraction layer on top of the RF Driver and is intended as a starting point for customers creating a proprietary Sub1-GHz protocol or application.

For more information see the ​EasyLink wiki page.

Serial Command API

Important Note: Using this API will not work on the default CoProcessor firmware flashed onto the GW16122. This requires the rfEasyLinkNp firmware example as provided in the TI SDK Download

The serial command API for the CC1350 is implemented in the form of standard AT+ commands that correlate to EasyLink API functions. This serial control method there has an example project provided by the TI resource center. The web page can be found ​here.

You can easily test the AT to Easylink api commands by using two GW16122/SensorTag devices running the rfEasyLinkNp and the rfEasyLinkRx examples.

Serial Format

Parameters offer set and get functionality.

  • The format of a parameter read command to get the TxPower parameter is: 
     “ATP00?”
  • The response to a read will be of the format shown below, depending on the parameter it will be hex or decimal: 
     “-10”
  • The format of an AT command to set the Frequency Parameter to 868MHz is: 
     “ATPFR=868000000”
  • The response of a write will be of the format:

Sample app to interface with 16122 running this software (link to it under software example section)

For further documentation on this serial implementation see the official ​TI wiki page.

TI 15.4-Stack

On the other hand, if you wish to create a full stack-based network solution, consider using the TI 15.4-Stack, available as part of the CC13x0 SDK.

The example lab documentation to get started can be found at the ​TI 15.4-Stack Project Zero page.

Further documentation can be found in the ​TI 15.4 User's Guide.

Texas Instruments Code Composer Studio

Code Composer Studio (CCS) is an IDE based on Eclipse and includes various libraries and software packages required to develop on many TI MCU's, including the CC1350 which is the primary component of the GW16122.

Below are some various notes on using CCS. See the ​Getting Started wiki and the ​Main CCS wiki for more information.

Resource Center

Click Menu item View -> Resource Explorer Expand software and view SimpleLink CC13x0 SDK as well as Ti-RTOS for CC2650 Drill down to the area you would like to explore Find an example, then click the download button to download to desktop Then click the import to IDE to import the project

Building a Project

Once the project is imported, right click on the project title in the explorer window and click 'Build Project' and let it compile. You can also click the debug button to build the project and run it on the connected target. Once it is complete, a binaries folder will be created under the project. Most TI tools will use the .out file that is produced there to program with.

Alternatively you can build projects via command line and avoid the entire IDE if you so desire. See the official TI wiki on ​Command Line Build/Create for more information.

A couple of additional notes when building via command line:

Note that the executable for Linux CCS installations is named "eclipse" and not "eclipsec" Run with "-ccs.help" to see full list of options Use full path names for all command line arguments (environment variables useful here)

General Notes

  • The XDS110 USB debugger referenced by material related to the CC1350 or in CCS is equivalent to the TiVa chip that's on the GW16122
  • Make sure the GW16122 is properly into the miniPcie->USB adapter board otherwise it will come up as a usb device but fail to be recognized by the code composer software. You can check if its connected properly by opening the .ccxml file under the projects targetConfigs folder and hitting the "test connection" button. If multiple boards are connected at once you will * need to specify them by serial number.
  • The US frequency allows for a total of 129 channels to choose from, defined in CONFIG_CHANNEL_MASK

You can prevent conflicts of sensor networks by either limiting the channels enabled on each collector/sensor, or by setting the PAN-ID to match on the devices belonging to each * network.

  • Beware of adding too many channels to your channel mask, for example, adding all of them took well over 20 minutes to complete the channel selection cycle and bring up the network.
  • Line of sight is extremely significant. Depending on the material, a few obstacles can drastically reduce your maximum range.
  • General RF information and specific information regarding antenna choice and performance can be found in this ​app note.

Programming the CC1350

The CC1350 of the GW16122 can be programmed a number of ways depending on your host machine. Gateworks has tested both Windows (SmartRF Flash Programmer) and Linux (Uniflash) tools but specific instructions will be provided from the Linux perspective.

You will need to have installed the software detailed in the Set Up section in order to continue.

The Uniflash tool is linux compatible and has both a gui and command line interface. The gui program has an autodetect feature and is somewhat easier to use but the command line tool has the same functionality and is better suited for repeated tasks with constant configurations.

  • Note that there doesn't appear to be a way to update the firmware on a running ARM based target. All of the methods we used to program the TiVa and CC1350 MCU's from a x86 host are not compatible with an ARM based system. This means that users will not be able to update firmware on running boards.

GUI Approach

  1. Connect a single GW16122 to the host machine (desktop/laptop) via mini-PCIe to USB adapter.
  2. Open the "Uniflash" application through a gui file manager from the uniflash_4.2 install directory, or via command line: 
    ./uniflash_4.2/node-webkit/nw
  3. Select target device of CC1350F128
  4. Select connection of Texas Instruments XDS110 USB Debug Probe
  5. Click the "Start" button

In the Program tab, select the firmware file you wish to load. This is typically a .out file created via a Code Composer Studio Project and can be found in your workspace directory (default ~/workspace_v7/)

  1. Click the "Load Image" and "Verify Image" buttons and see the text console output on the bottom of the window for a green success message

It should also be mentioned that you can program your GW16122 directly from the Code Composer Studio IDE by creating a proper target configuration and then selecting "Debug". Most of the TI example projects will detail this procedure.

At this point you may want to power cycle your device.

Command Line Approach

  1. Navigate to your uniflash install directory 
    cd uniflash_4.2
  1. Run the installer providing a configuration and .out file as arguments, for example: 
    ./dslite.sh --config=CC1350F128.ccxml ~/workspace_v7/collector_cc1350lp/collector_cc1350lp/collector_cc1350lp.out

The CC1350F128.ccxml file can be created via the uniflash gui or Code Composer Studio IDE. The contents of the file are provided in the collapsible text below for convenience.

CC1350STK Notes

The ​CC1350STK is a sensor node sold and designed by Ti. While similar to the Launch Pad, it is much smaller.

  • Button 1 is the button on the edge furthest away from the JTAG headers. This is labeled as the 'Power' button.
  • Button 2 is the button on the same edge as the JTAG headers. This is a 'user' button.
  • There is no green LED on CC1350STK. There is only Green LED on CC2650STK and that function is for CC2650STK.
  • Hex file to erase CC1350SensorTag_ExtFlashErase.hex
  • Hex file for default factory image: CC1350SensorTag_BLE_All_v1_33.hex
  • It's not possible to set the STK in factory restore by pushing buttons.
  • The Ti Bluetooth iPhone app is missing the 1Ghz factory image in the list of available firmware.
    • Files are placed here (typical installation path): *C:\Program Files (x86)\Texas Instruments\SmartRF Tools\BLE Device Monitor\firmware\cc1350\sensortag
    • rfWsnDmNodeOad_US_CC1350STK_TI_CC1350F128-v1_06.hex
