Hello All,
i'm a little clueless. I use a ESP32 with the Arduino IDE and the BLEDevice Lib.
From this lib I use the BLE Client Example. I have a BLE Device (LED Lamp) and want to turn it on and off.
With the NRF Connect App I figured out which Service and Characterisic is needed for this action.
If ...

jenrique_aguado I also used the iPad app.
But this doesn't change anything...I dont know what I am doing wrong

Thanks for your code, but I have the same problem as with mine.
I can connect to the lamp but it is not possible to change anything.

jenrique_aguado do you still have the code that was working?
Or can you see what the Problem with my code is?

Hi to all,

I'm new here. And I have a problem.
I have a Philips Hue ble bulb and I want to control it with a ESP32.
As a IDE I use Arduino. I took the BLE CLient example and used it.
