6.2 PRINCIPLE OF READING AND WRITING OF INTERNAL PARAMETERS
Document [DR1] details the exchanges modes, and their associated requests; with an aim of sending data to
a distant module.
This chapter details the data field in order to configure the internal parameters of the WaveTherm modules.
DATA Field
1 byte Max = 151 bytes
REQ_SEND_FRAME Applicative Commands Data
RECEIVED_FRAME
Acknowledgement of the
applicative commands
Data
There are two commands used to configure the internal parameters of the WaveTherm modules, and each
one has a corresponding acknowledgement command.
Applicatives
Commands
Description
0x10 Request of parameter(s) reading
0x90 Acknowledgement of the request of parameter(s) reading
0x11 Request of parameter(s) writing
0x91 Acknowledgement of the request of parameter(s) writing
Remark : In the command byte coding, the Response frame type are taking the Request command byte
value with the MSB bit set to 1.
It is possible to access up to 9 parameters simultaneously for writing or reading (all for
reading, or all for writing).

When a parameter is not known by the system, or the size is configured with a wrong value, the
corresponding data byte in response is set to 0xFF.
