Hi Bryan, I would be very interested in having some answers to your questions too! I'm trying to do the same, with an AD2P sink profile and an UDP socket to stream audio. But for now, i've got either packets dropped if the size of the queue which sends data from bluetooth callback to UDP socket is t...

I just did some other tests, by using unicast this time as I found that multicast can be an issue (https://tools.ietf.org/id/draft-mcbride-mboned-wifi-mcast-problem-statement-01.html). I've got very good results, even by using an ESP as Access Point (I miss the first packets, but then when I receive...

Hi everyone, I'm currently working on a bluetooth speaker project, and what i'm trying to do now is to create a network to share the audio between several speakers. I tried first to investigate solutions with the ESP-MDF, but apparently the mesh network doesn't support audio yet. So i decided to swi...

Hi everyone, I'm currently working on a project which uses two of those PDM mics: https://www.invensense.com/wp-content/uploads/2015/02/INMP621.pdf . For now, i'm saving some audio samples in flash memory, and then download them on my laptop, before opening the .pcm files on Audacity. I followed the...

Can you try I2S_CHANNEL_FMT_ONLY_RIGHT instead? I'm not sure if there is really a difference, but i saw many people use only instead of all for mono settings.

Is it mandatory to connect SELECT in case I use only I2S_CHANNEL_FMT_ ONLY _RIGHT / I2S_CHANNEL_FMT_ ONLY _LEFT options in config? I think it is. Take a look at the datasheet of the mic, even with mono, they connect the select pin with GND. I think the mic won't work (at least properly) if you don'...

This feature of receive audio data from bluetooth and then broadcast to other mesh nodes is not supported yet. But we have exploit a related feature: bluetooth beacon, it can be used in sales promotion, and the feature will soon be released. Okay, thanks for your answer. Do you know by any chance w...

Yes sorry, that exactly what i mean. But if it can't work and something else with bluetooth and mesh does, i'm still interesting!

Hi,

I'm using the ESP32 for an internship project, and I wanted to know if it was possible to use the mesh network of the ESP for sharing audio sent via bluetooth. I looked for the bandwith to know if it was enough to carry audio, but didn't find that info..
