How to determine Tx Power Level Value?

Yes, that's the way the TX Power Service is defined by the Bluetooth SIG. The document describing it is available here: https://www.bluetooth.org/docman/handlers/downloaddoc.ashx?doc_id=239393

Hi Ole, thanks for your answer.

In the proximity example ble_app_proximity, the TX_POWER service makes the characteristic tx_power_level available to client (readable). It is set to an initial value and is not changed over the time. Is that the whole intention?

There isn't any way to get the current TX power level from the stack, so if you need it you have to keep track of it in your application, based on your calls to sd_ble_gap_tx_power_set(). The default TX power level of S110 is 0 dBm.

For an implementation example of the TX Power Service, you can refer to the ble_app_proximity example in the SDK.
