Here is the format of these frame types:
•
Response received by host (RELAY_ROUTE_STATUS deactivated)
RECEIVED_FRAME
HEADER CMD DATA CRC ETX
3 bytes 1 byte 6 bytes variable 2 bytes 1 byte
0xFF ; 0x02 ;
0xXX
0x30
Radio address of
transmitting module
Data from received frame
Maximum size (N bytes) is defined below
0x03
•
Response received by host (RELAY_ROUTE_STATUS activated)
RECEIVED_FRAME_RELAYED
HEADER CMD DATA CRC ETX
3 bytes 1 byte 6 bytes 1 byte variable variable 2 bytes 1 byte
0xFF ; 0x02 ;
0xXX
0x35
Radio
address of
transmitting
module
Number of
repeaters
used
Radio
addresses of
repeaters
Data from received frame
Maximum size (N bytes) is
defined below
0x03
The field containing the radio addresses of the repeaters can be 6, 12, or 18 bytes, depending on the number
of repeaters used.
Defining maximum size
•
Point to Point mode Max = 152 bytes of data
•
Relay mode Max = 152 – (2 + 6 x Number of repeaters)
=> 1 repeater: 144 bytes of data
=> 2 repeaters: 138 bytes of data
=> 3 repeaters: 132 bytes of data
RECEPTION_ERROR frame format
With this command, the local Wavecard informs its host that a problem occurred during the exchange. This
command is forwarded between the Wavecard and its host using the serial link, and therefore does not
require a recipient's address.
Error messages are activated only if the EXCHANGE_STATUS parameter
is set to 0x01 or 0x03.
In the latter case, status messages are also activated but are not used in
this mode, but only when messages are sent without waiting for an answer
(MESSAGE and BROADCAST modes).
