LM074 SPP with GAP Central Application v1.1

vii. Start and end of report is mentioned.

viii. E.g. In above report, row “= 3 : 1032-00-5b0002 : 0203”

mentions module has 3rd connection with 1032-00-5b0002 device

and CID given by BLE stack is 0203.

ix. CID given in above response is referred while reading/writing data

with AT commands, reporting disconnection, notification etc. User

should note this carefully.

x. Response to this module depends on current state of the module

for BLE connections.

xi. In a scenario where module has established 3 connections as

shown above and if it drops connection 2 then the response to

command AT*BLECONN=? Will be

at*BLECONN=?at*BLECONN=?

REP*:BLE_CONN

= 1 : 3333-33-333333 : 0101

= 2 : Open

= 3 : 1032-00-5b0002 : 0203

= 4 : Open

= 5 : Open

REP*:BLE_CONN END

3.5.3 “AT*LECONN”\r\n

i. Execution only command

ii. GAP Central application gives more details on connection

parameters when connection is successful and error code value if

connection fails.

iii. User need to mention the BD address of the remote device with

which the BLE connection is to be established, e.g.

“at*leconn=1031-00-5b0012”\r\n tries to establish connection

with “1031-00-5b0012” device.

iv. Response to this command will be ERR if any of the following is

true

a. string format is incorrect

b. BT address is invalid

c. 5 BLE connections are already established

v. Response to this command will be OK if all the following

conditions are true

a. Command string format is correct

b. BT address is valid

c. Module has at least one BLE connection open

vi. After displaying OK response, module starts the BLE connection

procedure.

vii. If the connection is failed the report is given with the error code e.

g. “REP*:BLE_CONN_FAIL:=1031-00-5b0012,4

err_code:0014”\r\n.

viii. Refer the Error code list mentioned in the appendix section.
