Thanks again, I tried a few times today with jump lead hooked up to a running vehicle, the voltmeter on the dash was showing over 14v. Same results
gets to 2% read then fails, reads really really slow. I tried a few baud rates from 10400 to 124800 same results. The log file shows the same as normal it looks like the errors starts like this
