 == Sending BLE Packets over GATT ==
+
+Now that the packet structure and values are established, the candle can be controlled by the Gateworks SBC & GW16126 BLE card.
+
+The following was done with a Gateworks Ventana SBC using Ubuntu Bionic software.
+
+1. Load the following modules
+{{{
+modprobe algif_hash; modprobe algif_skcipher; modprobe algif_rng; modprobe algif_aead; modprobe af_alg; modprobe hci_uart;
+}}}
+1. Start the bluetooth daemon
+{{{
+bluetoothd -E &
+}}}
+1. Find the device the bluetooth is connected to
+{{{
+dev=$(basename $(ls -d /sys/bus/usb/drivers/ftdi_sio/*/ttyUSB*))
+}}}
+1. Attach bluetooth to inferface dev
+{{{
+btattach -B /dev/$dev -S 1000000 -P h4 &
+}}}
+1. Now scan for BLE devices and confirm we have found the candle
+{{{
+hcitool -i hci0 lescan
+}}}
+1. Change the color of the candle to red:
+{{{
+gatttool -i hci0 -b 3C:A3:08:10:51:FE --char-write-req -a 0x002e  -n 56ff000000f0aa
+}}}
+1. Change the color to green:
+{{{
+gatttool -i hci0 -b 3C:A3:08:10:51:FE --char-write-req -a 0x002e  -n 5600ff0000f0aa
+}}}
+
+== IoT and Beyond ==
+
+The LED Candle is only an example. 
+
+BLE can be used for many industrial sensors, such as tags for location information.
+
+The CAT M1 modem on the GW16126 can then further enable internet connectivity, allowing sensor data to be pushed to the cloud.
