3.4. Synchronous Band Rate (RFC2217)

Synchronous baud rate is named RFC2217. USR Similar RFC2217 make adjustments on the basis of RFC2217 protocol

to improve accuracy of transmission. Enable the baud rate function of WIFI serial server via AT command:

AT+AABR=on
This command takes effect immediately and does not need to be restarted. After restarting, the WIFI serial server will

restore the previous baud rate.

3.5. RFC2217 Protocol Description

Protocol length is 8 bytes. And values taken for example is in HEX:
