5. COMMUNICATION MODES

This chapter covers:

•

The methods for using Wavecard's four communication modes

•

Command format

•

Corresponding parameters

5.1 Frame exchange mode

This type of radio exchange allows you to send a request and then wait for a response from remote modules.

Following transmission of a radio frame, the Wavecard radio stays in

reception mode for a period specified by the parameter

RADIO_USER_TIMEOUT

. This allows the unit to receive a response from

the remote module.

The RS232 serial connection is not managed during this phase. This

command is generally intended for reading Wavenis-based telemetry

modules (temperature measurement, humidity, liquid flow, tank levels, digital

state management).

5.1.1 Configuring parameters

Frame exchange parameters are accessible

REQ_READ_RADIO_PARAM

and

REQ_WRITE_RADIO_PARAM

. Parameter details are provided in Appendix III of this guide.

NUM

DESCRIPTION

VALUE

SIZE
(in
bytes)

0x04

RADIO_ACKNOWLEDGE
Indicates whether or not radio frames
should be acknowledged by receiver.

0: no acknowledgement
1: with acknowledgement (default value)

0x06

RELAY_ROUTE_STATUS
Parameter related to relay route
transmission in each relayed frame
received.

0x00: Relay route transmission deactivated
0x01: Relay route transmission activated
By default, relay route transmission is
deactivated.

0x07

RELAY_ROUTE
Table containing radio addresses of
successive repeaters used to reach the end
module.

BYTE 1: number of repeaters in route.
Maximum number of repeaters = 3
If BYTE 1 != 0
BYTES 2 to 7: Radio address of first repeater …,
etc.

1 to 19

0x0C

RADIO_USER_TIMEOUT
Specifies time-out for receiving response
frames

Value in multiples of 100 ms
Default value = 0x14 (2 seconds)
