SiK Radio

SiK radio is a collection of firmware and tools for telemetry radios.

Information about using SiK Radio can be found it the PX4 User Guide: Telemetry > SiK Radio

The ("developer") information below explains how to build SiK firmware from source and configure it using AT commands.

Build Instructions

You will need to install the required 8051 compiler, as this is not included in the default PX4 Build toolchain.

Install the toolchain:

brew install sdcc

Build the image for the standard SiK Radio / 3DR Radio:

git clone https://github.com/LorenzMeier/SiK.git
cd SiK/Firmware
make install

Upload it to the radio (change the serial port name):

tools/uploader.py --port /dev/tty.usbserial-CHANGETHIS dst/radio~hm_trp.ihx

The radio supports AT commands for configuration.

screen /dev/tty.usbserial-CHANGETHIS 57600 8N1

Then start command mode:

DO NOT TYPE ANYTHING ONE SECOND BEFORE AND AFTER

+++

List the current settings:

ATI5

Then set the net ID, write settings and reboot radio:

ATS3=55
AT&W
ATZ

You might have to power-cycle the radio to connect it to the 2nd radio.
