3.1.1 - Format of the internal parameters access
The Wavecard equipment manage internal parameters mainly relative to RF features. RS232 commands
allow to access these parameters in read or write mode. Default values are set at the first initialization of the
product.
REQ_READ_RADIO_PARAM command is used to read parameters and REQ_WRITE_RADIO_PARAM is
used to write parameters. Each parameter must be accessed individually.
