From: Ben Whitten <ben.whitten@xxxxxxxxx> The SX125x family are IQ radio transceivers from Semtech configured over SPI, they are typically connected to an SX130x series concentrator however may be connected to a host directly. Required properties include the radio number of the host or concentrator bus.
