Detailed Description

Default Group Function Handler for PGN 126993 - "Heartbeat".

This PGN shall be transmitted by all NMEA devices. Reception of this PGN confirms that a device is still present on the network. Reception of this PGN may also be used to maintain an address to NAME association table within the receiving device.

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.
