4.2.4 Frame for updating the value of specific registers
This frame (0x41) allows to change the value of requested registers.

Description of the frame :
• Byte 1: CONF ID1 (8bits) : indice of the first register to change. The corresponding register is 300 + value of
CONF IDX. For example, if CONF ID1 = 0x14 (hexadecimal, so 20 decimal), the product will change the value
of register number 320.
• Byte 2: value to assign to CONF ID1 : in this example, its value has a size of 1 byte
• Byte 3: CONF ID2 (8bits) : indice of the second register to change. The corresponding register is 300 + value
of CONF IDX.
• Bytes 4 and 5: value to assign to CONF ID2 : in this example, its value has a size of 2 bytes
• …
The product does not return any uplink frame following the reception of a downlink frame 0x41. However, the Con-
fig bit of the status byte (see section 4.1.1.2) will be set to 1 in the next scheduled uplink frame (periodic or alarm
or keep alive frame) if all was well done.
IMPORTANT: the value 0xFF for a CONF IDX will stop the reading of the downlink frame. Only the bytes preceding
this value 0xFF will be taken into account. This mechanism can be useful when you need to work in fixed downlink
frame lengths and you do not want to use all available bytes.
