Polling mode exchanges do not use the values set in the
RADIO_ACKNOWLEDGE parameter.
5.4 Broadcast mode
This mode allows a transmitter to address a request to all Wavenis modules within radio range. You do not
have to specify the address of each remote module.
Depending on the command used, requests can either wait or not wait for a response
(REQ_SEND_BROADCAST or REQ_SEND_BROADCAST_MESSAGE commands). In either case, there
are two types of exchange in broadcast mode:
• Non-selective broadcast: queries all modules within radio range
• Selective broadcast: only queries a given group of modules within radio range
5.4.1 Configuring broadcast mode parameters
Parameters are accessible using REQ_READ_RADIO_PARAM and REQ_WRITE_RADIO_PARAM
commands (all parameters are listed in Appendix III).
