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:
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.
