Hi.

You can disregard my previous answer.

Turns out that both the scanner and the advertisers use the same radio_config () API for setting the radio parameters. So technically, scanner API does not have to set the TX power, it could be leftover from legacy code.

Best regards,

Hi.

Not 100% sure why we set tx power in scaner_init().

But I assume that it is related to what is explained in this case:
https://devzone.nordicsemi.com/f/nordic-q-a/37928/just-set-tx-power

"As a peripheral, any connection inherits the TX power that was set for the advertising role (BLE_GAP_TX_POWER_ROLE_ADV), so you only need to set it once before the first connection is made to get the same behavior as before. For the central it is the same, you only need to set it once with the scanner/initiator role (BLE_GAP_TX_POWER_ROLE_SCAN_INIT)"

I'll double check with our Mesh developers, and get back to you.

Best regards,
Joakim
