I have made many projects working on CAN-BUS and most of them are by using the Niren type CAN-BUS module.
Recently I bought 10 modules from ebay and to my surprise I noticed that they don't work on extended mode but on standard they do! I am using the last Seed-Studio library. I have an other UNO with a SeedStudio CAN-BUS shield on it and I have performed the following tests:
- Standard Mode: CAN-BUS Seedstudio -> Niren Works.
- Standard Mode: Niren -> CAN-BUS Seedstudio Works.
- Extended Mode: Niren -> CAN-BUS Seedstudio Works.
- Extended Mode: CAN-BUS Seedstudio -> Niren NOT WORKING!
So it does send a correct message on extended mode but cannot receive one which is very strange..
Has anyone faced the same problem? This happened only in the last batch I bought and are from this exact auction:
Is there a solution or do you know of any true reliable source for these modules?
