Payload description
If you want to connect to your own server, it is necessary to decode the specific payload for each
device. To accomplish this, a payload decoder is required, which can be downloaded using the
following link:
Payload decoder . Extended documentation of the protocol can be found in the Payload
description on our website. An example payload produced by YO Distance is presented below with
divisions for each measurement and marked with decoded values, whose interpretation is described
in the
Payload description .
