El cheapo dongle

Before you read on: this post in not an endorsement whatsoever. We stick 100% to our advice to either build a CanSee dongle if you want fast&furious, or buy a KONNWEI 902, as that is about the only dongle that is a fairly stable build for fairly cheap.

Having said that, as a sort of fun/silly experiment stemming from the “Use ISOTP fields” mode I wrote about earlier, I decided to order the absolute cheapest dongle I could get, and ended up with a usual “blue transparent case” model for under 2 Euros.

Guess what, it has a decent PIC processor, external EEPROM, Bluetooth 4.0 chip, and an Atmel (Microchip) CANbus transceiver. This is not some hacked together crappy thing with half baked software in the spare capacity of some Bluetooth controller. And here comes the unbelievable part. After some tweaking, I got it running with CanZE. I literally had to change two lines of code in the development branch. Which I will have to cross check with my KONNWEI dongle of course. I was honestly flabbergasted.

    What does the “Use ISO-TP” mode do by the way?

    So, is the ISO-TP mode about producing the ISO-TP frames manually over what the dongle normally offers?
