There is no config file for chan_usrp. It's setup in app_rpt. rxchannel = usrp/127.0.0.1:34001:32001 ; ipaddress_to_use:output_port:input_port On 01/28/2016 02:58 PM, Stephen - K1LNX wrote:
Thanks Steve, I really need to get off my duff and start playing with this thing. Are thereany example configs for USRP anywhere (assuming it even needs one)? I looked through your GitHub source tree as well as my own test vm I built, but nothing glares out at me.

Stephen, DMRGateway was created with the idea of how do we get audio in and out of asterisk without any modifications to asterisk or app_rpt. chan_usrp fit the bill perfectly. It provides a simple way to send and receive audio (PCM) and the signaling (COS and PTT) needed.

Mike.... this is good stuff, and congrats on your achievement!
I am still largely new to this as you aware, but in the ASCII diagram you provided you mention "DIAL w/ USRP" ... just to clarify, is that the USRP channel driver or a USRP itself, or both? Just trying to get a feel for what might be needed to support this for myself from a hardware standpoint.

Progress has been made. I finally got a chance to focus back on the return channel of the gateway and it works. I have had successful QSOs using the new code where:
Analog Radio <----> DIAL w/ USRP <----> DMRGateway <----> DMRLink <---> TG9998
This was a full two way path with the DV3000 doing both encode and decode. ambe_audio.py has been extensively modified to support the return channel and DMRGateway is tasked with the Allstar to DMR linkage.
This code is not ready for prime time yet (the configuration files need to be updated with additional values, error checking, code cleanup/refactoring) but an Alpha release will be available to all testers soon.
Once the code is cleaned up all source will be released to allow others to modify/extend.
I specifically want to thank Cort for his amazing code base. Without it, there is no way I could have added this functionality. Open source rocks. This is so cool, thanks!!!!
