Hi Michael
I found some time for the "hanging upgrade" issue since we splitted the
vehicle ID from VWUP to VWUP.T26 and VWUP.OBD.
Would this code in ovms_config.cpp within OvmsConfig::upgrade() prevent
the "hanging" after an upgrade?
// Migrate vehicle ID VWUP to VWUP.T26if (GetParamValue("auto",
"vehicle.type") == "VWUP") { SetParamValue("auto", "vehicle.type",
"VWUP.T26"); SetParamValue("auto", "vehicle.name", "VW e-Up (Komfort
CAN)"); }
If so, I would put that in a pull request as soon as we have a new
"release worthy" version?
Thanx for checking.
