Coronis Wavenis Wavecard User Manual

Wavecard-Waveport User Manual Coronis Systems
5.3 Polling mode
Polling mode allows you to send a request to a predefined list of remote modules. Responses are sent to the
host that originated the request when all remote modules have responded or after a time-out. The are two
types of exchanges in polling mode:
Non-selective polling All remote modules designated in the POLLING_ROUTE table are queried.
Selective polling Only a selected group of remote modules listed in the POLLING_ROUTE
are queried.
5.3.1 Configuring polling mode parameters
Polling mode parameters are accessible via REQ_READ_RADIO_PARAM, and
REQ_WRITE_RADIO_PARAM commands (a complete list is provided in Appendix III).

WAVECARD_POLLING_GROUP: Byte
containing the Wavecard's polling group.
Byte 1: Polling_Group
By default, Polling_Group = 0x00

POLLING_ROUTE: Table containing the
radio addresses of remote modules to query.
Byte 2 : number of modules to query

Bytes 3 to 8 : radio address of the first
module, second module, etc.

in polling mode.

POLLING_TIME: time delay between two
consecutive transmissions in polling mode
Value in multiples of 100 ms
By default, POLLING_TIME = 0x0A

Example
This example shows how to write list of the remote modules to query in polling mode. Suppose we have two
remote modules, whose 6-byte addresses are 0xAAAAAAAAAAAA and 0xBBBBBBBBBBBB. Launch a
REQ_WRITE_RADIO_PARAM request, setting the CMD byte to 0x40. Then, in the DATA field, specify the
number of the parameter to be modified and corresponding data using the following format.
DATA field
1 byte variable
Number of the parameter to modify Parameter data
Thus:
REQ_WRITE_RADIO_PARAM
Header CMD DATA CRC ETX
3 bytes 1 byte 1 byte variable 2 bytes 1 byte
0xFF ; 0x02 ;
