How to configure BLE transmit output power classes

[Duracell]

Hi all

I am looking for a way to configure the BLE radio transmit output power to class 3 (range < 1m) for advertising packets.
According to the datasheet this should be possible.

I could not find any API to do this.

Anybody knows how to do this?

I already tried changing BTM_BLE_ADV_TX_POWER in bt_target.h but this had no effect.

Any help is greatly appreciated.

Thanks
Dura

This works now with the latest version from master.

There are new functions in bt.h:

Code: Select all

/**
 * @brief  Set BLE TX power
 *         Connection Tx power should only be set after connection created.
 * @param  power_type : The type of which tx power, could set Advertising/Connection/Default and etc
 * @param  power_level: Power level(index) corresponding to absolute value(dbm)
 * @return              ESP_OK - success, other - failed
 */
esp_err_t esp_ble_tx_power_set(esp_ble_power_type_t power_type, esp_power_level_t power_level)
