[Ovmsdev] UDS/ISO-TP Query

Hello One & All, I am in the process of getting the smart ED (451) working on v3, have not had an issue getting data out via normal PID requests. However I am having issues with talking to the BMS & Charger, it might me being a noob, but I can't work out the best way to do UDS/ISO-TP. For instance I need to send the following packet to: 0x7E7 03 22 02 08 FF FF FF FF I need to then pick up the following from 0x7EF: 11 93 62 02 08 0E A7 0E I also need to send flow control frames, basically speak ISO-TP. I can see in the TR code how to send a frame via CAN, however not sure how to pick up the response and talk ISO-TP Hope that makes sense, Thanks Fran
