Thank you ESP_Sprite for the tip.
It should not be connected to anything but i will double check

Thank you for the answer chegewara.
Just tried that but same behavior.

Hello forum, I put an ESP32-WROOM-32D on my board with a 6 pins connector to flash it. The connector provides 3V3 / GND / RXD / TXD / EN / IO0 On a small board i made a adapter that works with an FTDI USB/Serial cable, using two transistors to drive EN and IO0 from DTR and RTS. I made it from the ES...

ok thank you i will do that.

Thanks chegewara for the answer, When i compared the code of the two examples gatt_server and gatt_client i found that it looks easy to mix the two of them. So i did it, the server started ok, then i started the client with a scan, found my device but strangely when i connect to the device with a ca...

Hello,

Thanks for any help !

I'm sending a pure sinus from my phone and i get a square (at the right frequency) even at low volume. Besides it seems that...
