Did some refactoring in ambe_audio.py and will check in the changes soon.
We have started posting the code needed to create the IPSC to AllStar gateway.
The 2 repositories that we will use are:
DMRlink <https://github.com/N4IRS/DMRlink>
This is forked from the original author Cort N0MJS so that we can track the changes needed. If you are going to create and maintain a gateway, you will need to learn and understand DMRlink. It's written in python and runs fine on a RPi. DMRlink is the connection to the IPSC network. The changes are in ambe_audio.py. It has been modified to send the frames out via UDP. There is a added configuration file and a updated subscriber ID .csv file One of the sample programs you want to look at is playback.py This is the code used to create the echo or parrot TG for listening to your own DMR audio.
DMRGateway <https://github.com/N4IRS/DMRGateway>
This is the code used to get the AMBE frames from DMRlink via UDP format them and send to the DV3000 via UDP. The returned PCM (analog) is sent via UDP to the asterisk USRP channel driver. The code will be posted as it's cleaned up and prepared for human consumption. ;)
Our next step is to build the analog to DMR path. DMRlink provides all the pieces needed to do this.
