Convert the operation status of 'Connect' to 'Standby'
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 Promi-SD 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'
unexpectedly. Notice that Promi-SD holds data transmission when it encounters '+', until
receiving next character.
'+' is an escape sequence character by default, which is changeable by AT+SETESC.
AT+SETESC, ATO, AT+BTCANCEL
