By default, the UART data rate is set to 2.4 kbit/second at the factory. This data rate can be
changed by setting the regDATARATE register. The data rate should be limited to 9600 bits/sec
when in narrowband mode. Exceeding this rate will result in poor link quality. Valid settings are:
Baud Rate
2400
9600
19200
38400
57600
115200
10400
31250
Table 7, Data Rate Register Settings
TROUBLESHOOTING HINT: Baud Rate Problems. If you lose track of the baud rate setting of
the module, it will be impossible to program the module. You can either try every possible baud
rate to discover the setting, or force a power-on reset with CMD held low to set the baud rate to
its default: 2.4kbit/second.
