2.1.2 API Configuration

When using the patch some changes have to be done to the API exported from SmartRF Studio. formatConf.bMsbFirst in CMD_PROP_RADIO_DIV_SETUP must be set to 0 to allow for LSB to be transmitted first and maxPktLen in CMD_PROP_RX must be set to 0 for unlimited packet length. The RX bandwidth should be set to 39/38.9 kHz (CC13x0/CC13x2), and a good starting point for the deviation is to set it to half the data rate (see Table 2-3).
