If you want to use an RNode with amateur radio applications, like APRS or a packet radio BBS, you will need to put the device into TNC Mode. In this mode, an RNode will behave exactly like a KISS-compatible TNC, which will make it usable with any amateur radio software that can talk to a KISS TNC over a serial port.
Whether you RNode is bought from my shop, made from a compatible LoRa board or built by yourself, you can use the RNode Configuration Utility to change settings on your device, including putting it into TNC mode.
The easiest way to install
rnodeconf on your system is via
pip. You probably already have
pip installed if you use a relatively recent version of Linux or macOS. If not, go and install Python 3 now. When that is done, you can simply install
rnodeconf by opening up a terminal and typing:
pip install rnodeconf
After a few seconds, the program should be installed and ready to use. If this is the very first time you are installing something with
pip, you might need to close your terminal and open it again before the
rnodeconf command is available. With the program installed, you can put your RNode into TNC mode simply by entering the command:
rnodeconf -T /dev/ttyUSB0
Remember to replace
/dev/ttyUSB0 with the actual port your RNode is connected to. The program will now ask you for the channel configuration parameters, like frequency, bandwidth, transmission power and so on. It is also possible to specify all the parameters at once on the command line, see the
rnodeconf --help for information on how to do this.
That's all there is to it! Your RNode is now configured in TNC mode, and ready for use with amateur radio applications.
