Raspberry Pi Zero w as bluetooth transmitter

Mon Aug 26, 2019 10:10 am

Hi! I want use Raspberry Pi Zero w as bluetooth transmitter.

But when i use command " arecord | aplay -D sabluealsa:DEV=A0:E9:DB:01:24:F0 ", i have this information:

"
pi@raspberrypi:~ $ arecord | aplay -D sabluealsa:DEV=A0:E9:DB:01:24:F0
ALSA lib pcm.c:2565:(snd_pcm_open_noupdate) Unknown PCM bluealsa:DEV=A0:E9:DB:01:24:F0
aplay: main:828: audio open error: No such file or directory
Recording WAVE 'stdin' : Unsigned 8 bit, Rate 8000 Hz, Mono
"

If i use test: aplay -D bluealsa:DEV=A0:E9:DB:01:24:F0 piano2.wav
All work ok.

I want grab signal from USB-Audio, from microphone ( input ), and transfer to bluetooth device with bluealsa. :D

What is 'sabluealsa'? I've never heard of it, and neither has Google, and neither has your Pi, unsurprisingly.
