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! ---

The internal logic of the audio channels in app\_rpt are designed exclusively for CM108/CM119 audio systems. ---

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. > **[GitHub - baresip/baresip: Baresip is a modular SIP User-Agent with audio and...](https://github.com/baresip/baresip)** > > Baresip is a modular SIP User-Agent with audio and video support > **[Setting up a SIP Phone - AllStarLink Manual](https://allstarlink.github.io/adv-topics/sip-phone/)** > > AllStarLink Manual ---

Huh, this is a really unique approach to the problem. Thank you! It's a little over my head, but I'll give it a shot. ---

ChatGPT can help with BareSIP and Asterisk/Allstar configuration. ---

Hi Eric, I have bluetooth audio enabled and connected, Baresip installed and configuredin ASL3. Now what do I do? Thanks ---

So now you should be able to call your node from BareSIP. Just dial the node number like you're calling an extension on a PBX. Once connected you can connect to another node using \*3NNNNN. Then when you're connected to the other node you use \*99 and # to key up and key off. To disconnect the node use \*1NNNNN. ---

Eric, Thanks for your answer. Apparently Baresip is looking for alsa. But Asterix is not ready to play with alsa and I had to install pulse audio. Can baresip work with pulse ausio? ---

I really don’t know. Probably should research it yourself and report back. > **···** > > > On Aug 19, 2026, at 14:45, psv [noreply@community.allstarlink.org](mailto:noreply@community.allstarlink.org) wrote: > > > > > ![](https://community.allstarlink.org/letter_avatar_proxy/v4/letter/a/bb73d2/45.png "AB2ZT") | [AB2ZT](https://urldefense.proofpoint.com/v2/url?u=https-3A__community.allstarlink.org_u_ab2zt&d=DwMCaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=sNNtlSpPfcfoYeq1Y4xnuYTlBD1phVI1iY9joZNiweA&m=2SKo8hGGLWnEEAX0RpFmLnMQGz-kJ5hKN1mmuUYyVPBpcYqnW_Zsa2nCueexSrHw&s=-nTO5aJATMpwGFar5gRIeeCEDPZkotuWKMGS9hrQ3Nc&e=) > > > August 19 | > > > > > > - | - | > > > > Eric, > > > > Thanks for your answer.

Ok, I got pulseaudio installed and configured in baresip. OS speaker-test works with the BT headset. But baresip /dial fails with timeout. I can connect to my node using the the ASL3 tel number and pin. But no audio...
