ATIM_ACW-TMxP_UG_EN_V1.0
Downlink
This functionality is available on ACW-TMxP fulfilling the following conditions:
Application software
Radio firmware
SIGFOX version
V0.0.1
V5.9.3.1
LoRaWAN version
V0.0.1
v4.0.0
The operation of the Downlink is explained in the document ATIM_ACW-DLConfig_UG_FR_v1.4, relating to version
V1.2.0 of the ATIM Downlink Protocol (see this document for all parameters and commands common to all products).
The parameters specific to ACW-TMxP are as follows:
a.
Configuration of the frame parameters (sending period, number of samples, etc.)
For byte 4, the two bits YY correspond to the history depth
–
1 (max = 3) and the three bits ZZZ correspond to the
number of samples per frame
–
1 (max = 7).
Bytes 5 and 6 correspond to the period for sending a frame (= 0xYYZZ) ranging from 1 minute to 255 hours (15,300
minutes).
Example
: Byte 4 = 0x13
4 samples per frame + addition of the four samples sent to the previous frame.
Byte 5 = 0x3C and byte 6 = 0x00
Sending period = 0x003C = 60 minutes
b.
Number of probes
Parameter code (Byte 1)
Parameter value (Byte 2)
0x17
0x00 = no probes enabled
0x01 = only 1 probe enabled
0x10 = only 2 probes enabled
0x11 = both probes are enabled
