BLE transmit power - how to set?

[Josegm]

Hello everyone,

I'm trying to find how to where the BLE TX power is set and if it's possible to change it.

Is it part of the PHY settings?

Thank you for any pointers.

Hi,

Sorry that it can not be set right now, but it may be supported in the future.
We will let you know if there is any update.

Thanks for your interest in ESP32 !

Hi,

any update on this?

I'm also still looking for some way of changing the TX power level for BLE.

Also what is the power level used currently? I see the only mode available is dual Classic/LE (ESP_BT_MODE_BTDM) so does this mean the TX power is dictated by the lowest denominator, +4 dBm, for both LE and Classic?

I really wish more resources were put into the Bluetooth side as single chip combined WiFi+Bluetooth is one of the key differentiators of the ESP32 vs ES8266, Realtek RTL8187 and others.

Hi

I'm also very interested in knowing how to set the BLE transmit power. My current measurements indicate a power consumption around 100-110 mA (with WIFI disabled) which is way above what is needed by nRF52832 to transmit BLE. I'm aware that it is BLE 5 but still it is hard to have it run on batteries charged by solar panels which I want.

Please give some insights.

Thanks
