SENA Parani-BCD110 - Manual (Page 47)

Description In ‘Connect’ status, data from host is transmitted to the other side Bluetooth device, and
any AT command is not accepted but this command, which is not echoed on the screen.
When Parani-BCDx10 encounters a character ‘+’ from host, it stops the data transmission
and waits for next 2 characters. If the next 2 characters aren’t both ‘+’, it restart to transmit
data including the first ‘+’ as well. If not, it converts the operation status to ‘Standby’.
If the data from host includes ‘+++’, it will convert the operation status to ‘Standby’. Notice
that Parani-BCDx10 holds data transmission when it encounters ‘+’, until receiving next
character.
‘+’ is an escape sequence character by default, which is changeable by AT+SETESC.
