In case of error
If the numbers of the requested recordings doesn't exist, then the response frame will have the following
format :
Contents of the response RECEIVED_FRAME
Data Field (max : 152 bytes)
Applicative
Command
Frame number
1 byte
2 bytets
0x86
0xFF : Error
Attention, if the number of requested recordings is higher than the number of available recordings,
then :
- The WaveTherm – DALLAS returns the error frame.
- The WaveTherm – PT100 returns the available recordings.
- The WaveTherm – PT1000 returns the available recordings.

In case of success
The size of the information returned by the Wavetherm module is such as the radio module must transmit
several radio response frame.
The module uses the Multi-Frame mode of the Wavenis protocol which allows to optimize the radio
exchanges with the interrogator equipment. It successively transmit to the interrogator equipment several
frames containing the recordings from the most recent to the oldest one.
The radio acknowledgement mechanism is automatically activated by the WaveTherm, when successively
transmitting its response frames.
