Hi all,
I'm working on an embedded device, that runs Linux 4.14.79, that has 2 hardware PCM, one connected to a bluetooth chip and one to a GSM phone.
My goal is to bridge those streams (bt-capture -> gsm-playback and gsm-capture -> bt-playback) in a fullduplex configuration to handle calls. In fact, the bluetooth will be connected to an handset.
I was testing different asound.conf configuration, but I cannot figure how to automatically route those streams. So far I've got (not posting all the attempts, only the part I think is ok):
pcm.bt {
type hw
card 0
format "S16_LE"
channel 2
rate 8000
}
pcm.gsm {
type hw
card 1
format "S16_LE"
channel 2
rate 8000
}
type hw
card 0
format "S16_LE"
channel 2
rate 8000
}
pcm.gsm {
type hw
card 1
format "S16_LE"
channel 2
rate 8000
}
I probably need to use the asym plugin, but I cannot figure how to bind them.
Is my goal achievable?
Best regards,
Gabriele
