Can we have two microphones on the robot and receive stereo sound? I have been thinking about a game of marco polo where the marco can hear in stereo with video turned off. If anyone is not familiar with the game : https://en.wikipedia...arco_Polo_(game)

Currently not supported by Vigibot. You can add this support request in suggestion and idea.

Anyone want to make an advanced audio low latency project ? Just ask and I add the feature. -> For now it's low latency 16KHz@16-bits PCM, it's very heavy, but very optimized for high voice quality (but not for music), 2ch is a huge loss of eficiency because it need twice the bandwitch (already too large) or half the quality (8-bits sound /OR/ 8KHz samplerate become unbearable !!!!) . For 99% usage on vigibot it's a regression because Smartphone are mono (#1 visitors use smartphone) / All small USB mic on the market cleanly supported by Linux are mono / Using sterero need headset or fixed large speakers and large-special USB soundcard and microphone on the Raspberry PI... Also for ADSL2+ disabling the sound is recommended because in many case bandwitch for the sound become larger than bandwitch for video!!!! But if anyone really want to make this audio (or any other) project with this easy-to-add missing feature (or any other, just ask) I can do this stereo-support in few hours. This would be an option disabled in the factory configuration. But I never add stereo support myself on vigibot without concrete usage from >= 1 real user.

i gave up trying to configure the bluetooth speakers as I can't figure out how to use the higher quality profile! (the low quality profile is really bad)
if anyone knows how, let me know.

Bluetooth relie on serial port, on the official vigibot image I moved the good serial port for robotics use and the bad serial port to bluetooth because near useless for robotics
To try the bluetooth disable the vigibot modification before
but you can't use the serial port anymore

[firened]

yes i did that.
removed bt_disable in config.txt
enabled hciuart.service and bluetooth.service

perfect
for a No GPS and No arduino robot it's perfect

Le micro fonctionne sur une PI Zero?

[firened]

it should

[Serveurperso]

No, because audio need a lot of CPU power and PI Zero already to slow for all...
