Radio communication

The TYNESS-FIX-RAIL periodically sends its sensor measurements via a LoRaWAN™ radio link.
In order to configure the Tyness sensor on a LoRaWAN™ network, you must have the unique EUID identification code, indicated on each product, as well as the two AppEUI and AppKey codes supplied with the sensors at the time they were ordered.

You can also find all the keys and identifiers using the TyNess configuration software. See “CONFIGURATION SOFTWARE”.

Various communication parameters can also be modified using the configuration software, such as ADR validation, or the periodic reJOIN procedure.

Payloads descriptions

The Tyness sensor transmits its data in raw format on different public and private LoRaWAN™ networks.
The following section explains how to decode these received frames (PayLoad)

Periodic frames

The periodic frames contain the data measured by the Tyness sensor.

Example of a periodic transmitted frame (HEXADECIMAL):

Periodic frames (continued)

The frame described above can also be transmitted in 2 batches, if the channels are not synchronized.
This gives the following frames:

 

About the Object Type byte:
The object Type byte indicates the type of measurement performed by the sensor (see following table). It also contains 2 bits providing additional information:

Sample frame with channels and errors

The following frame comes from a TyNess with a rogowski card on socket 0 and a PT100 card on socket 1, and only one PT100 probe connected on channel 2:

 

Status frame

The status frames contain additional information about the sensors (battery level, firmware version, etc.)
