Hi Bruno,

The short answer is GATT_WriteCharValue(connHandle, &req, selfEntity);

But, for more detail, I suggest reading over the BLE/BLE5 User's Guides to see how this is done in code.

I suggest reviewing the simple_central code too as a guide to mimic. I hope this helps. If you have more questions, feel free to follow up in a new thread!
