ESP32 I2S Audio
Posted: Wed Jun 15, 2022 9:06 am
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
