ESP32S3 : What is the BLE output power when using Bluedroid ? How to change it ?

Postby ThomasESP32 » Fri Mar 14, 2025 8:56 am

Good morning,

I am using the Esp32S3 with the Bluedroid stack in order to send/receive BLE informations.
I would like to know the BLE output power of the chip but I don't know where to find this information.

Is it possible to know this ? Is it set somewhere in the firmware when starting the BLE stack ?
Is it possible to change the output BLE power ?

Could you please tell me as much information as you can concerning this point or
could you please tell me where to find these informations ?

Thank you for your help,

Best regards,

Thomas TRUILHE

You can modify the BLE output power. The Bluedroid stack in ESP-IDF allows adjusting the power level using the esp_ble_tx_power_set() function.

Hello,

thank you for your answer !

Do you know what is the BLE output power if the function has not been called ? Let's say the "default" output power ?

Best regards
