Hi ESP_Lvxinyue,

Hi, I are using ESP-WROOM-32 in an application. Please provide the following details regarding ble transmission of ESP-WROOM-32.

1) modulation bandwidth ,
2) frequency channels and
3) data rate.
4) Tx Power

Can we change above parameters programatically? If yes, please tell how to change these ...

I designed a development board based on ESP32-WROOM-32 . Initially everything worked well. But suddenly my ESP32 stopped working :( . After debugging, I found out that ESP-32 module's power pin (3V3) and Gnd pin showing connectivity. I don't know why this happened.

At what situation this happens ...
