Uplink frame formats
a. Sigfox and LoRaWAN
The data are different depending on the type of frame sent out. The frames specific to the ACW-TM1D use the
following format:
Description Frame format
oct 0 (dec) oct 0 (hex) oct1 oct2 oct3 oct4
Keep-alive frame 1 0x01 Supply IDLE voltage Supply Tx voltage
Test frame 5 0x05 Test counter
Temperature S1 < lower threshold and
temperature S2 < lower threshold 83 0x53 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 < lower threshold and
temperature S2 between thresholds 84 0x54 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 < lower threshold and
temperature S2 > upper threshold 85 0x55 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 between thresholds and
temperature S2 < lower threshold 86 0x56 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 between thresholds and
temperature S2 between thresholds 87 0x57 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 between thresholds and
temperature S2 > upper threshold 88 0x58 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 > upper threshold and
temperature S2 < lower threshold 89 0x59 Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 > upper threshold and
temperature S2 between thresholds 90 0x5A Digital temperature - sensor 1 Digital temperature - sensor 2
Temperature S1 > upper threshold and
temperature S2 > upper threshold 91 0x5B Digital temperature - sensor 1 Digital temperature - sensor 2
BEWARE: Probes 1 and 2 each have a low threshold and a high threshold that is specific to them.
The temperature is calculated with the following formula:
Digital temperature * 0.0625
BEWARE: A temperature value equals to « 0x8000 » indicates a measuring error. This is often due to a loose cable.
b. Example
Example of frame received: (hex) 5801900300
‘Frame type’ = (hex)58 = 88 => ‘
Temperature S1 between thresholds and temperature S2 > upper threshold
’
‘Digital tem perature - sensor 1’ = (hex)0190 = 400 => ‘Actual temperature’ = 400*0.0625 = 25°C
‘Digital temperature - sensor 2’ = (hex)0300 = 768 => ‘Actual temperature’ = 768*0.0625 = 48°C
Example of frame received: (hex) 55FDD00348
‘Frame type’ = (hex)55 = 85 => ‘
Temperature S1 < lower threshold and temperature S2 > upper threshold
’
‘Digital tem perature 1w - sensor 1’ = (hex)FDD0 = - 560 => ‘ Actual temperature ’ = -560*0.0625 = -35°C
‘Digital temperature 2w - sensor 2’ = (hex)0348 = 840 => ‘ Actual temperature ’ = 840*0.0625 = 52.5°C
