Fixed. Caused by a scan result coming in after switching off wifi. (Todo: replace remaining ESP_ERROR_CHECKs in the Wifi module by real error handling) Regards, Michael Am 08.01.2018 um 08:24 schrieb Greg D.:
Hi folks,
Another crash. Not repeatable, but wanted to report it before I head up stairs to end the day.
I had booted the module, modem off, obdii ecu started, v2 server enabled but not connected. Wifi was started but the local network is hidden, so it wasn't connected. This is all in the startup event script. OBDWiz dongle running, all fine. The plan was to let it run for the night, to catch any longer-term reboots, so I needed to turn off the wifi in order to keep the screen from filling up with 'incorrect scan type' messages. Hit wifi mode off, and it crashed (see below). Doesn't appear to be a memory issue. Tried it a second time, and wifi stopped as normal.
{sigh} Definitely time for bed...
