I am also looking for a way to configure the 500mW TX Power. I have found a lot of ambiguous information since the user manual says TX Power is up to 316 mW and several datasheets and brochures mention 500 mW…
Is there really a way to transmit at 500mW or is it a theoretical maximum power??? How can we configure the radio to transmit at 500mW if the TX Power parameter goes from 0 to 4, 4 being 316mW?
