Web30 jul. 2012 · When Serial data is transmitted to an Arduino, it is sent one byte at a time. Even though you might type “123” in the Serial Monitor, that’s not quite what is sent. Instead the bytes “1” then “2” then “3” are sent. Once received into a buffer on the Arduino, these individual bytes need to be reassembled into something useful. WebThere may be more efficient standardized protocols, or you can make up your own. If you just need an extra couple of bits you can use part of the message ID as data. Using CAN B you have 21 bit CAN IDs and you can probably use 8-16 of these bits as data depending on how many actual message IDs you need in your system. 3.5K views View upvotes

Web21 aug. 2015 · That buffer is empted by sending the data a byte at a time using an interrupt. If you are in an interrupt (at a higher priority than the serial interrupt) then the interrupt that sends the data can never happen, so the buffer just fills up and stops when it gets to 64 bytes. In general, sending multiframe payloads is not supported by plain ELM327 devices. Although with some crude combinations of ATR0 and ATR1 or alternatively appending 0 and 1 to your frames to distinguish whether you want a response or not, you could do it in theory, but it's pretty unreliable on most adapters.
