Outgoing connection command: "AT‘conn:00126l357215“\r\n
“OK“ response will be provided if the string entered has valid BT
address, module is not connected to any device.
“Err" response will be provided if invalid BT address. invalid length
of address is provided or if the module is already in connected
state.
After module gives OK response to at+conn command. it starts the
connection procedure. Result of connection procedure is indicated
as indication message.
1. “IND':CONN_FAILURE:OO126f35721S" message is shown
to indicate the failure in connection with ED address 0012-
6f-357215.
2. “IND‘:CONNECTED:00126i3S7215" message is shown to
indicate the SPP connection is successfully established and
the devices are in connected state.
3. Once the devices are connected. LM951/LM961 is in SPF-
connected-online-data mode. Every string entered by host
on UART is treated as data and is transmitted to connected
device.
4. User can come out of this mode by entering the Escape
sequence.

If the user issues scape sequence in SPP-connected-onlinedata
when LED D10 is Blinking, OK response is given by module and
module enters in SPF-connected—online-command mode.
Once the module enters in SPP-connected—online-command mode.
any strings entered on UART are considered as AT commands and
are processed by module (still the module is in connected state).
In SPF-connected—online-command mode, users can query/update
module settings and start the disconnection by issuing at'drop
command.
