3.8 Verification of LMU configuration for BLE “connection” mode example.
LMU BT driver “DISCOVERED” state can be verified by observing the following debug log
lines:
“BLE rx cmd:DISCOVERY,2,9059AF0AA9A9,0,-67,1,020105”
LMU BT driver “CONNECTED” state can be verified by observing the following debug log
lines: “BLE rx cmd:CONNECT,1,1,0,9059AF0AA9A9” , where 1 is the connection handler
index, 1-Low Energy mode, 0 – not paired, 9059AF0AA9A9 – remote device address.
The line: “BLE: Connected” indicates that the connection is achieved.
It is important to note that the connection handler index is returned by BTCS and is arbitrary
number ranging from 0 to 65535. The same connection handler index must be used to send
the user messages as explained in 4.1.
ATCS? Command will return the connection handler index:
SERMSG: Rcvd Msg:
41 54 43 53 2C 31 2C 31 2C 30 2C 39 30 35 39 41 46 30 41 41 39 41 39 0D
The above debug log line when converted to ASCII format is: ATCS,1,1,0,9059AF0AA9A9
where 1: connection handler index, 1: BLE mode, 0-not paired, 9059AF0AA9A9
is the BLE remote device MAC address.
3.9 Verification of LMU BLE “Advert broadcast scanning” mode
configuration example.
The debug log indicates when the final LMU BLE “Scanning” state is reached by:
BLE: Scanning
The KeyFob “Button 1 Press” event user message looks like the following:
SERMSG: Rcvd Msg:
44 49 53 43 4F 56 45 52 59 2C 32 2C 30 30 30 37 38 30 36 37 41 33 35 44 2C 30 2C 2D 36 36

The above message when converted to ASCII format looks like the following:
DISCOVERY,2,00078067A35D,0,-66,3,020106-020A03-0501FFFF5B01, where
2 is the GAP advertising report type: LE Connectable and undirected, Connectable
and Scannable, 3 – LE Connectable Direct Advertisement, Connectable only, 4- LE
Scannable Indirect Advertisement, Scannable only, 5- LE Non-connectable Indirect
Advertisement, Not connectable or scannable, 6- LE Scan Response.
00078067CD72 is the MAC address.
0-public, 1- Random LE address type.
-66 is RSSI Received Signal Strength indication value of the last packet received in
dBm.
