Detailed Description

Default Group Function Handler for PGN 126464 - "PGN List - Transmit/Receive PGNs group function".

Note: This handler is mandatory for NMEA 2000 certified devices.

The PGN List group function type is defined by the first field. The message will be either a Transmit PGNs or a Receive PGNs group function that identifies the PGNs transmitted from or received by a node.

◆ HandleRequest()

bool tN2kGroupFunctionHandlerForPGN126464::HandleRequest	(	const tN2kMsg &	N2kMsg,
		uint32_t	TransmissionInterval,
		uint16_t	TransmissionIntervalOffset,
		uint8_t	NumberOfParameterPairs,
		int	iDev
	)

Handle response for request group function.

Default response is "not supported". Certified devices must have inherited handler and respond for requests for all device transmit PGNs.

Use GetRequestGroupFunctionTransmissionOrPriorityErrorCode to get error code for transmission interval/offset request. If that returns N2kgfTPec_Acknowledge, modify your PGN transmission interval/offset according to request.

Handler must returns true, if it handled request, false otherwise.

See example of overrided handler on

tN2kGroupFunctionHandlerForPGN60928::HandleRequest

Parameters

N2kMsg	Reference to request group function message (PGN 126208)
TransmissionInterval	Transmission interval [ms]
TransmissionIntervalOffset	Offset to the transmission interval [10ms]
NumberOfParameterPairs	Number of parameter pairs contained inside the group function message
iDev	Index off the device in tNMEA2000::Devices

Return values

true	If request was handled.
false	If request was not handled.

Reimplemented from tN2kGroupFunctionHandler.
