Macchina A0 dongle not working/Simos tools

Hello all,

Sent in a support ticket for what seems like a faulty Macchina A0 dongle however have not yet gotten a response back from Sparkfun, so hence I’m posting here.

My issue is essentially that the A0 dongle, after having its firmware updated, it does not seem to want to connect to Simos Tools app once plugged into the OBD port. The light on the dongle does not turn on. What’s weird is that when I was first setting it up the light was clearly on. However once I got it all set up the light does not come on and I can’t get it to connect to Simos tools. It has never been connected to simos tools and I bought the dongle new from Sparkfun.

Followed this to get it set up: Simos Tools - Getting Set Up — Data Driven MQB

Any one had this happen to them? Is the light supposed to be on when connected? Am I missing something?

Sorry about the message getting lost in the shuffle!

Can you try loading the default firmware and testing to see if that works? You can use Torque or similar Firmware Reference | Macchina Docs
