Baud Rate
This command will change the baud rate of the main serial UART. The parameter is a single
ASCII coded hex character according to the following table.
Table 9 Baud Rate

If the baud rate setting is successful,
the module will respond with a “CMD OK” at the
original
baud rate and then immediately update to the new baud rate. If the setting is unsuccessful,
an error message will be returned at the original baud rate and the baud rate will remain
unchanged.
Note the RBM101 is based on a Silicon Labs Flex Gecko radio. This device
uses an automatic gain control on the radio that can make the RSSI reading
non-linear and inconsistent as gain is added to the rx circuit. Use at your
own discretion.
