ESP32 I2S Audio

[slippen]

Hi,

I'm using a ESP32 as I2S Master to feed a Teensy 4.1 with Bluetooth Audio. It worked fine for more than 100 hours than bluetooth started with noise and failed working 2 hours later.

ESP32 can still be programmed but bluetooth is not avaiable any more. Same behavior with a spare part.

I'm using a stabilized 5V regulator for both teensy and esp32 and it looks fine.

Any ideas what may have destroyed the bluetooth part on ESP? (It's an AZDelivery ESP32 Dev Kit C V4 )

Kind regards
Franz
