Hi, I'm trying to connect to my custom sensor that is the BLE server. My esp32 S3 is the Ble client. I'm using example ble multiconnect example, where i merged ble_client _security into it.

Re: BLE peripheral. gatt_server_service_table to start with my project?
Thanks a lot for your reply,
I measured the consumption, and with this exemple i get 100mA continous.
It is really too much for my batterie application even if i play with sleep mode.
Is it possible to reduce it drastically? ( around 30 or 40mA should be good)

ESP32 GeekWom board I2c not square and wrong freq: Picture
Hi every body, I'm developping an app with i2c device, and i am really surprised to see my signal really not square, it is like there is a capacitor effect on the ligne. I also don't understand why signal frequency equal around 73khz, while i set 100khz. I am connecting on pin 19 for scl and pin18 f...
