1. Optimal settings can be used to optimize power consumption when the output power is NOT 22 dBm (high power) or
14 dBm (low power). In that case, a dedicated firmware configuration associated to a dedicated board matching network
(see AN5457 for details) corresponding to the custom output power, can be used.
