J1939 Parser

[dakriege]

Hi, I have a modified version of your driver working with an ODB2 MX+ reading data from a Ford F53 RV Chassis. I added commands to read the vehicle information and DTCs.

We switched from a Gasoline RV to a Diesel RV sitting on a Freightliner chassis with a Cummins diesel. It uses J1939. The MX+ module supports ELM 327 / J1939 but now I need to develop a parser.

Have you done any experimenting with J1939 ?

Hi, no, I've no experience with J1939.
I'd expect the MX+ to wrap that all and work with the same commands though.
If that's not the case you'd have to find some kind of documentation of the messages, with that it should be quite easy to add a parser for it.

I exchanged notes on the ScanTools.Net Blog. ScanTools MX+ supports J1939 on the network side but their software doesn’t support it. You can do ELM 327 / J1939 AT Commands but the application layer is completely different than OBD2. It would be a start from scratch development. I found a Bluetooth Low Energy J1939 adapter that has free Android / IOS applications and they published an API on GitHub for a Windows Framework application. It uses the Win10 BLE library - I’ve done some other BLE stuff so I’ll use that as a starting point to create my Windows Service Thanks, Dave From: DarthAffe [mailto:notifications@github.com] Sent: Monday, September 14, 2020 5:21 PM To: DarthAffe/OBD.NET <OBD.NET@noreply.github.com> Cc: dakriege <dakrieger@ameritech.net>; Author <author@noreply.github.com> Subject: Re: [DarthAffe/OBD.NET] J1939 Parser (#20) Hi, no, I've no experience with J1939.
