TX Power of connection partner ("Central")

[takashina hiroki]

I have a question about TX Power.

SDK: 15.3.0
Example: ble_app_multirole_lesc
Device: EYSHJNZWZ (nRF52832)

The device operates as a “Peripheral”.
Is there a way to know the TX Power of connection partner ("Central") when the device is connected to "Central"?
If possible, please tell me how.

Hi

If a receiver is going to know the transmitters' TX power, this information has to be put in the payload when the transmitter sends advertising packets.

Best regards,

How do I put TX Power into the payload when the transmitter sends an advertisement packet?
Also, how can I know the TX Power of the transmitter at the receiver?

Hi

This will be the way to get the transmitter's TX power at the receiver. You usually set the TX power by using the sd_ble_gap_tx_power_set() function. Then, you should be able to add that value to your advertising data. Our Bluetooth Low Energy Advertising tutorial describes how to do just this in "Challenge 1".

Best regards,
