The MGM210P is based on the EFR32MG21 SoC that has 2 RF ports: RF2G4_IO1 and RF2G4_IO2.
The RF2G4_IO1 port seems to be connected to the internal antenna and the RF2G4_IO2 port seems to be connected to pin 29 of the module throught a matching circuit.
When using the module as a NCP application with the EmberZNet SDK, how the RF port can be selected?
How the RF2G4_IO2 can be enabled if we would to use an external antenna instead of the module internal antenna?
Is-it the setting in the "hardware configurator" of Simplicity Studio in Radio / "Antenna Diversity"?
In the EZSP reference guide, there is also a value "EZSP_VALUE_ANTENNA_MODE".
