Multipacket messages using PGN EB00

Post by eugen.berenstein » Mon 17. Mar 2025, 16:04

Hello,

Is multipacket transfer (using PGN EB00) already implemented by the API?
Or should we listen to EB00 and EC00 messages and reassemble them manually?

Thanks for the feedback

Hello,

the API implements the transport protocol (BAM and RTS/CTS) as specified by the J1939 norm and the recommended practices 1210. In order to be able to send/receive large J1939 messages (data length > 8) you need to claim an address (Protect_J1939_Address), and also be sure that you let the API do packetizing (parameter nIsAppPacketizingIncomingMsgs of the function RP1210_CLIENTCONNECT set to 0).
Best regards,
Keneth
