This command set the baud rate of the UART communication. The input parameter
is single digit number in the range of 0 to 7, representing baud rate from 2400 to
921K, as shown in table 3. Notice that when baud rate is set to 2400, there is no
need to wake up RN4020 for UART communication.

3.2.1.4 SC,<hex32>
This command sets the supported client services. The input parameter is 32bit
bitmap, which indicates the services this device supports as client role. When
corresponding bit is set, the service is supported as client role in this device.
Supporting a service as client role means all characteristics of such service on the
peer device could be accessed, if the peer device as server role supports such
service. The bit map of supported services could be seen in table 4.
