Hello,

I must admit I didn't read the thread, I just noticed the original post mentioned the zephyr/subsys/bluetooth/services/tps.c which I believe is what you are looking for here?

To understand what the BT_GATT_SERVICE_DEFINE() does here you can go to 27:20 in this webinar:

Thank you Kenneth,

The discussion you linked to does not provide information on how to actually implement the TPS (TX power service) and the HCI power control example that you linked to does not use the TPS either (I have used this sample before). I have also read the specification on the TPS from Bluetooth SIG and it does not provide information on how to incorporate the TPS in an application's source code.

How do I implement this service so that I can read TX power from the central?

Thanks
