I'm trying to set the PAwR response power level on an ESP32C6 in this example https://github.com/espressif/esp-idf/tree/master/examples/bluetooth/nimble/ble_pawr_adv_conn/ble_pawr_adv_conn to ESP_PWR_LVL_P20 (20dBm).

But it doesn't seem to work despite doing that with:

esp_err_t err = esp_ble_tx ...
