Hello, I was trying to change my firmware from V3.0.0 to V3.3.1.
On turning the ignition on the message came up in the screen shot attached:
received 0xc0 (off-key).
Can't read MCU info. Could be protocol error.
(or forgot to set single wire mode?)
What is single wire mode? What does it mean by protocol error? What do I need to do to fix this? please make the explanation pretty basic as this is not an area I have any expertness in.
It was working fine before I did this, I haven't tried it since, I'm assuming it failed to make any changes.
