4.2.3 Specific register VALUE request frame
This frame (0x41) allows to change the VALUE of requested registers.
0 1 2 3 4 5 … 7
Code PAYLOAD
0x40 CONF ID1 CONF ID2 CONF ID3 X X X CONF IDn
Description of the frame:
• Bytes 1 to N : CONF IDX (8bits): index of the register to be sent. The corresponding register is 300 + CONF IDX VALUE .
For example, if CONF ID1 =0x14 (so 20 in decimal), the product will send back the value of register number 320.
The associated uplink frame has the code 0x31 (see paragraph 4.1.5).
0 1 2 3 4 5 … 11
Code PAYLOAD
0x31 Status VALUE 1 VALUE 1 VALUE 2 VALUE 3 VALUE 3 X
In this example: CONF ID1 is a 2-byte register, CONF ID2 a 1-byte register and CONF ID3 a 2-byte register.
If an error is detected in the request, the returned 0x31 frame will be empty.
IMPORTANT : The user can specify several CONF IDs in his downlink frame but it is his responsibility to verify that according to the protocol the
size of the data available in a downlink frame will be large enough to contain all the desired data. Otherwise, the application will only send the
first VALUEs.
