ESP32C3-WROOM BLE max power settings

[stevasway]

Hi all,
inside the ESP32C3-WROOM datasheet is written the max RF power control range : 18 dBm.
Is it possible to set this maximum power range?

Using Arduino Core, the code is

esp_err_t errRc;
errRc = esp_ble_tx_power_set(ESP_BLE_PWR_TYPE_DEFAULT,ESP_PWR_LVL_P18);

is it correct? And more, the tx power is effectively set to max?

Thanks all!
