Another stable dongle?
Göran Nybom reported on the issue tracker that the Vgate iCar 3 ELM327, which at least seems not to be some no-brand-with-always-changing-guts dongle, works fine. Price seems fair (20-ish), and it’s smaller than the KONNWEI which people might like.
This is no endorsement, we don’t have one, but if you do, please comment with your results, so we can update the hardware page. Or send it to me 😉
Edit: unfortunately, the one I received did not support the ATAL command and contained a main controller with a scraped off top marking. So unfortunately, I cannot honestly recommend buying Vgate, at least not from Aliexpress or Ebay. it seems that these are carbon-copied too. Well, the shell at least.
