Hello everyone, I have set up two allstarlink nodes in the past one using a Yaesu FTM-150 radio and ARA-1+ sound fob, the other using a Kits4Hams radio hat.
This time I'd like to see what it would take to use a bluetooth headset, specifically my David Clark HBT-30. It pairs directly to my RasperryPi and even has a button that I'm sure could be programmed to function as PTT.
It's my understanding that AllStarLink needs a CM108 audio chip, but there has to be some way to get this to work without a USB audio adapter.
Just looking for anyone that can point me in the right direction. Thank you!
Theoretically, I guess someone could create a client that sends/receives to/from app_rpt using USRP, and supports Bluetooth PTT/audio. Analog_Processor from DVSwitch could probably already handle the audio part. Don't know what you'd do for PTT, though.
Other than that, the only option I know of would be to use something like an Allscan UCI80 or another K-connector type URI and one of those K-connector compatible Bluetooth microphones sold for use with Baofeng and similar HT's. AFAIK, they're all pretty terrible, though.
I just bought one for the express purpose of seeing how bad it is.
There is ongoing work to abstract the audio channel drivers to remove the ties to CM1xx devices. However it will make configuration a lot more complicated when it comes to GPIO mapping.
Have you been able to pair it with your Raspberry Pi? If it shows as an audio device in ALSA you should be able to install a soft phone app like BareSIP and follow the instructions for setting up SIP phones.
