Hi,

0x3004 here is BLE_ERROR_INVALID_ADV_HANDLE, so this means that you have provided an invalid handle value to sd_ble_gap_tx_power_set(). You call this function twice, both for a connection, and for the advertising role. For a connection, you need to pass the connection handle of an active connection. And for advertising, you need to pass the advertising set handle that you got from the call to sd_ble_gap_adv_set_configure(). From the code you have posted it does not seem like you have any of these yet, and in that case this cannot be set (it is premature).
