AT+ UARTTLN<CR>
<CR><LF>+OK=<time,length><CR><LF>
Set

AT+ UARTTLN=<time,length> <CR>
<CR><LF>+OK<CR><LF>
Parameters

time: Byte interval between packets,0～255 ms.

length: Maximum length of a packet,0～1460 byte. If the interval is not reached and the received packet length

reaches the maximum, the packet is packed and sent.
E.g.AT+UARTTL1=0,0

2.5.17. AT+RFCENN

Function

Query/set RFC2217 baud rate synchronization of PortN
