Is it possible to still use A2DP with ESP mesh running. I have a product under development where one, or more, of the nodes needs to drive sound to selected headphones near it. I have looked and note the wifi/mesh interoperability but not BT Classic/A2DP and mesh. I'm using Wrovers so have the extra...

By the way - I have previously used touch sensors which used a static DC voltage to read the touch sensor - in this situation I drove a plane behind the sensor using a DAC with the average analog sense voltage on the touch pin - this worked very well. The trouble I have with the ESP32 is that it dri...

I'm working on a product development using a touch wheel based on the ESP32 touch sensors. The ESP32 is very close behind the touch wheel and the grounded meta cover is messing with the sensitivity. I could design in a driven shield plane between the touch sensors and the ESP32 metal case but don't ...

Thanks for responding. I guess I'm trying to implement some audio functions with ADF but don't use the line or mic in and am happy with 8-bit internal DAC and A2DP for audio output. I have space issues and want to avoid using a codec chip if I can. I have a LyraT unit I'm which using for development...

Thank you for your information.

Hi there. I have a product under development which has a handheld BLE server controlling 3 clients - probably with SPP. The questions I have are: 1). I assume I can connect with more than one BLE device at a time?? Any points on how to do/where to look. 2). If I know the BD name etc of the clients -...

Thank you. I can confirm that I have success delivering various tones to standard A2Dp headset at a sample rate of 44100. The big problem now is that the after 110 seconds from connecting the A2DP disconnects - then reconnects for another 110 seconds and repeats. I have looked around the code and ca...

My product (in development) mainly sends data direct to phones/speaker via Bluetooth a2dp. The source is wav, mp3 files (on sdcard) and program-generated tones. I have managed this part without use of the codec but I also want to capture new files received over http coded into mp3 and stored on sdca...

Thank you so much for your reply,

I guess I missed it as it doesn’t use a pipeline/stream.

Can I assume that the format is:

Sample Rate: 44100
Data size: 16 bits
Format: L-R. 16 bit little-endian?

Thank you again.
