  1. Hi everyone, I bought a PmodESP32 evaluation board to test the ESP32 module. In my project I would like to use classic bluetooth (no low energy). When I power up the system and do a scan with a smartphone, the ESP32 module does not appear. If I try to use the AT commands (AT + BTINIT ...) the module replies with an error message. I'm pretty sure the system firmware needs to be updated, so i tried to do a firmware upload but without success. I used various software (Arduino, ESP DOWNLOAD TOOL V3.8.5) but during the procedure it seems that the module is not recognized.
