We will expand this article with more examples in time.
Please refer to this article for the message specifications. These are just examples.
Here is an example payload, as sent from the Sigfox backend to your server. It fills the 12 bytes of allowed payload.
0x98: Heading = 304 degrees.
Remember, raw is in 2 degree units.
0x00: Heading = 0 degrees.
Verbatim copy of downlink: XXXXXXXXXXXXXXXX. This will be the downlink you sent to the device. 8 bytes long, made according to the integration spec.
Here is an example of an extended GPS data uplink, which includes GPS position accuracy, at the cost of other precision.
"Heading": 315 degrees. Mask off the E nibble of the E3, and multiply by 22.5 degrees.
"Latitude": 1.3401344. Convert to the signed integer value (7DCC00 [little endian] -> 52349 [dec]) and then multiply by 256/10'000'000.
