Bluetooth TX Power

[aircable]

I noticed that when advertising with BLE, the output power on the ESP32 is really really low. Where is the API to configure the BLE power level? I could not find anything.
Please tell us how to change the RF transmit power when using BLE.
Thanks

It seems like the radio is configured to the minimum output power, index 0

/* adv tx power level */
#define BTM_BLE_ADV_TX_POWER_MIN 0 /* minimum tx power */
#define BTM_BLE_ADV_TX_POWER_LOW 1 /* low tx power */
#define BTM_BLE_ADV_TX_POWER_MID 2 /* middle tx power */
#define BTM_BLE_ADV_TX_POWER_UPPER 3 /* upper tx power */
#define BTM_BLE_ADV_TX_POWER_MAX 4 /* maximum tx power */
typedef UINT8 tBTM_BLE_ADV_TX_POWER;

With this as the output power configured as: (from bt_target.h)
#define BTM_BLE_ADV_TX_POWER {-21, -15, -7, 1, 9}

Can someone show how to adjust the output power?
It's really vital that this can be increased from the -21dBm

@aircable I hope you have got solution. Please share it if you can

Também estou com o mesmo problema!
Não consigo comunicação entre dois esp32 acima de 5 metros via bluetooth.
Se alguém souber como resolver esse problema, por favor compartilhe conosco.
Obrigado!

Does esp_ble_tx_power_set works?

I have not used this before.
