Is it possible to increase bluetooth transmit power in stm32wb55rg?

[POrlo.2]

Hi 

I have two stm32wb55rg nucleo which i will use to transfer data via bluetooth for each other.

I would like to use an external antenna like the ant0060. However, I did not notice any change in the receiving range after changing the gain antenna from 3.3 dbi to 5 dbi.

The code is used from the project:

GitHub - stm32-hotspot/STM32WB-BLE-PER-Testbench: Example demonstrates how to enable BLE Direct Test Mode (DTM) in the STM32WB from a firmware user application using HCI testing commands directly to perform a Packet Errror Rate (PER) measurement

Is it possible to change the transmit and receive power by the stm32wb55rg chip itself?

Hello,

You can set the TX power level of the device using ACI_HAL_SET_TX_POWER_LEVEL command, the maximum value is 6 dBm.

If you want to increase the output power to 20 dBm, you can use an external power amplifier, for more information you can look AN5395.
