Here is the format of these frame types:
• Response received by host (RELAY_ROUTE_STATUS deactivated)

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 Waveport CF informs its host that a problem occurred during the exchange.
This command is forwarded between the Waveport CF 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).
