Features

The Silex SX-NEWAH module featuring the Newracom 7292 features:

IEEE 802.11ah operating in Sub 1GHz license-exempt band
- Offers a much greater range over 2.5GHz and 5GHz technologies
- Offers a much higher data rate than proprietary Low-Power Wide-Area (LPWA) technologies such as LoRa and Sigfox
- Full IP stack lowers barrier to entry over proprietary Low-Power Wide-Area (LPWA) technologies such as LoRa and Sigfox
Latest generation Wi-Fi security - WPA3
Channel widths: 1/2/4MHz channel widths with optional short guard interval (SGI) (yield 150Kbps to 15Mbps PHY throughput at the PHY layer but due to USB-to-SPI and driver polling maxes out at about 3-4.5mbps)
Streams: 1 spatial stream
Data rates: MCS0-MCS7, MCS10 (1MHz only)
Client / Node count: 8,191 theoretical (no security). With security, it will be less due to memory limitations, but over 1000 clients have been confirmed working with security enabled.
Country: US support only
Modes: Infrastructure, Monitor. Contact Gateworks support if interested in 802.11s mesh.
Auth / Encryption: Open, WPA2-PSK(AES), WPA3-OWE, WPA3-SAE
OFDM modulation
AES-CCMP encryption
750 to 950MHz frequency band
TX gain range: 23dB
RX noise figure: <4dB
Max input level: -10dBm
Dual embedded ARM Cortex-M0 and Cortex-M3 processor
SPI host interface
Only 1 GW16146 is supported on a give system; as there is no concrete way to associate SPI bus number with particular device. The bus number assignment relies on USB bus scan and device probe sequence

See rate table at: https://en.wikipedia.org/wiki/IEEE_802.11ah
These are maximum PHY data rates - actual throughput depends also on packet loss and most importantly SPI and USB bus overhead and latency which effectively reduces throughput of the GW16146 to a max of around 4.5mbps.
Range is affected by BW used. 1MHz should be used for long range applications. See some example range by BW here: https://youtu.be/Y_qmCR1so2c?t=188

Software

Software support consists of the following items: (This a summary. Details are below)

Linux kernel driver for FT232H as a USB to SPI bridge on the GW16146
Linux kernel driver for the NRC7292 SPI Radio chip
Firmware files required for NRC7292 driver in /lib/firmware: nrc7292_cspi.bin and nrc7292_bd.dat
Userspace cli_app application to performing miscellaneous configuration via Netlink to the NRC7292 driver

The above software support is present in the following:

Venice Ubuntu Jammy (22.04) pre-built images
Newport Ubuntu Focal (20.04) pre-built images.
Ventana Ubuntu Focal (20.04) pre-built images

FT232H USB to SPI bridge

The FT232H features an multi-protocol engine that can be used for UART, JTAG, SPI, I2C among perhaps other things. The FT232H's MPSSE is great for generating signals to communicate using the SPI protocol. The MPSSE can take care of generating a clock signal from about 450hz to 30Mhz, and read & write bytes of data at that frequency.

Gateworks has programmed the USB VID:PID on the GW16146 to 0x2beb:0x0146 which binds to the out-of-tree Linux kernel spi-ft232h driver.

When a GW16146 is found on the USB bus a SPI master host controller will be registered with the Linux kernel (which you can see in /sys/class/spi_master) as well as registers a nrc80211 SPI device which binds to the nrc7292 driver. Note that earlier versions of this driver required you to manually determine the SPI bus and manually probe the nrc driver with arguments pointing to the bus. Please make sure you are using the latest version of these drivers (available on the Gateworks pre-built Ubuntu based OS images) to avoid this (or refer to earlier documentation).

Building:

The driver compiles a single module 'spi-ft232h.ko' and can be built out-of-tree by assigning KDIR to the directory of your kernel:
```
KDIR=/usr/src/venice/bsp/linux make
```

NRC7292 kernel driver

The Silex SX-NEWAH module on the GW16146 has a Newracom NRC7292 which is supported by Newracom's open-source driver.

The Gateworks nrc7292 driver has some modifications to the Newracom NRC7292 driver:

add support for v6.2+
nrc-init: default to spi polling
nrc-hif-cspi: remove spam from spi_check_ready
nrc-mac80211: display wlan device registered
nrc: add display of driver version and chip identified
nrc: remove prints for non-errors

nrc7292 driver history:

v1.5 (Oct 2023) - Gateworks now supports this
v1.4 (June 2023) - Gateworks did not use this version of the driver
v1.3 (April 2021) - Gateworks original driver

There is a large set of kernel params (which you can see via 'modinfo nrc.ko') but for our purposes the following are needed:

fw_name - firmware file from /lib/firmware
bd_name - Board data file from /lib/firmware
spi_polling_interval - SPI polling interval in ms (recommend 5ms)

Example module loading:

modprobe fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_polling_interval=5

When using an OS like Ubuntu you create a file in /etc/modprobe.d/ to use these automatically when the module is loaded:

cat << EOF > /etc/modprobe.d/nrc.conf 
options nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_polling_interval=5
EOF

To find the correct wlan interface that is bound to the NRC7292 driver you can look at the devices in /sys/class/net to see which ones have a SPI based device-driver:

WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ -d $i/device/driver/spi* ]; then basename $i; fi; done)"
echo $WLAN
# wlan0

After bringing up the interface you can perform more configuration on it via the 'cli_app' (see below)

ifconfig $WLAN up

Building:

The driver compiles a single module 'nrc.ko' and can be built out-of-tree by assigning KDIR to the directory of your kernel:
```
KDIR=/usr/src/venice/bsp/linux make
```
Kernel Requirements: CONFIG_CRYPTO_CCM, CONFIG_CRYPTO_GCM, CONFIG_CRYPTO_SEQIV, CONFIG_CRYPTO_CBC, CONFIG_CRYPTO_CTR, CONFIG_CRYPTO_ECB, CONFIG_CRYPTO_AES

OpenWrt Information

For customers interested in OpenWRT, view repository link for NRC7292:

https://github.com/newracom/nrc7292_openwrt

cli_app

There is a 'cli_app' that is part of the driver code which communicates with the driver via the Netlink generic socket family API. Netlink is a Linux kernel interface used for inter-process communication between kernel and userspace similar to unix domain sockets designed for transferring miscellaneous networking information between kernel space and userspace processes. See https://en.wikipedia.org/wiki/Netlink for details.

The cli_app facilitates setting misc details that are not handled via iw. The app can be used in interactive mode by running without args or by sending commands.

Example usage showing useful features:

Configuration and Usage examples

Loading drivers:
1. lsusb shows GW16046 on bus with VID:0x2beb and PID=0x0146
```
lsusb -d 0x2beb:0x0146
# Bus 001 Device 003: ID 2beb:0146  
```
2. Load the NRC7292 driver providing the fw_name bd_name and spi_polling_interval parameters:
```
modprobe nrc fw_name=nrc7292_cspi.bin bd_name=nrc7292_bd.dat spi_polling_interval=5
```
  - after several seconds you should see a new wlan device under /sys/class/net
3. find the correct wlan interface that is bound to the NRC7292 driver by looking for a devices in /sys/class/net with a SPI based device-driver:
```
WLAN="$(for i in $(ls -d /sys/class/net/wlan* 2>/dev/null); do if [ -d $i/device/driver/spi* ]; then basename $i; fi; done)"
echo $WLAN
# wlan0
```
4. set the country code (required for newer versions of the driver)
```
iw reg set US
```
5. bring up the interface (required for configuration below)
```
ifconfig $WLAN up

Adhoc / IBSS Mode

Adhoc / IBSS Mode may only be supported with specific driver versions

Troubleshooting

Ensure the device can be seen on the USB bus:

# lsusb -d 0x2beb:0x0146
Bus 001 Device 003: ID 2beb:0146

Ensure the spi_ft232h driver is loaded

# lsmod | grep ft232
spi_ft232h             24576  0
# dmesg | grep ft232
[    7.555554] usbcore: registered new interface driver spi_ft232h

Ensure the spi_ft232h driver has registers a SPI bus:

# ls -l /sys/class/spi_master/ | grep ft232h
lrwxrwxrwx 1 root root 0 Aug 31 20:13 spi3 -> ../../devices/platform/soc@0/soc@0:bus@32c00000/32e50000.usb/ci_hdrc.1/usb1/1-1/1-1.3/1-1.3:1.0/spi-ft232h.0/spi_master/spi3

Possible regulatory domain issue:

Because there is not country set in the target, the target asserts. As was shown below and given here again:

[177933905] ASSERT(0) at CheckNUpdateCHTableByVif() in umac/umac_s1g_channel.c, 1033

Hardware

The Mini-PCIe connector on the GW16146 uses the USB channel only for communicating to the 802.11ah module. See below schematic for the connector.

J1 Test Debug Header

J1 is a header that is not loaded by default but can be loaded on 100 piece or more orders.

This header can allow for a direct UART connection to the SX-NEWAH chip.

Pin	Function
1	3.3VDC
2	MODE
3	UART_TX
4	UART_RX
5	Ground
