4.2.2 SIG Messages
The E104-BT12 module supports SIG Generic and Lighting HSL model control (see Mesh Profile and Mesh Model
introduction for relevant SIG message definitions).The SIG message format is as follows:
Send
Order
（
1byte
）
Target address (2 bytes)
Sig mesh message
0xC1
Primary address of Target
device
Request
Receive
Order
（
1byte
）
Target address (2 bytes)
Original address (2
bytes)
Sig mesh message
0x41
Primary address of Target
device
Source device master
address

For example: 1.Generic onoff control of Generic model:
Control the device whose main address is 0004, output
high level without delay
Request
09 C1 0004 8202 01000000
Respond 08 41 0004 0001 8204 01
Control the device whose main address is 0004, output low
level without delay
Request
09 C1 0004 8202 00000000
Respond 08 41 0004 0001 8204 00
2. Transparent transmission of information
E104-BT12 supports transparent transmission of user data. The maximum length of the serial port sub-packet is 60 bytes
(the maximum payload of a single packet in the bottom layer of the mesh is 8 bytes, and data larger than 8 bytes will be
automatically sub-packed and sent, due to the efficiency of the entire mesh network during the sub-packet sending
process. Not high, it is recommended to limit the data sent in a single time to less than 8 bytes), the data format is as
follows:
Send
Order
（
1byte
）
Target address (2 bytes)
Data
0xC2
Primary address of Target
device
Valid data
Receive
Order
（
1byte
）
Target address (2 bytes)
Original address (2
bytes)
Data
0x42
Primary address of Target
device
Source device master
address
Valid data
For example: Device 0001 sends the hexadecimal data of "00112233445566778899" to device 0004
