Hello @ljm 

This is possible directly throw CubeMX, just set the CFG_TX_POWER_MODE to 1 and you will be able to set the CFG_TX_POWER to 8dBm. You can still set this Output power throw: 

tBleStatus aci_hal_set_tx_power_level(uint8_t En_High_Power, uint8_t PA_Level);

with En_High_Power = 0x01 and PA_Level = 0x20.

Best Regards.
