mutliple Can frames for a single Msg

Post by krishna » Thu 3. May 2018, 22:57

hello
is there any way that I can send a Multiple Can frames at a time which belong to single message.
Ex: if the Message is of size 23 Byte and I want to send it once and on the other end I will be receiving 23 byte data so is there any way that using symbols or variables or multiplexer I can send it at once go and at the receive end I can receive the whole frame in single multiplexer.
Is there any way that I can send a multiple packets at a time which represent a single message.

A CAN 2.0A/B Frame could send max. 8 Data Bytes. If you need to send more Data Bytes in a CAN2.0A/B Frame, you need to create your own "protocol" to send multible CAN Frames - or you use a High Layer Protocol which includes this feature. (Like J1939, ISO-TP etc.)

If you use CAN-FD, you could send in one CAN Frame up to 64 DataBytes.
