Hi folks, This is different... I've been playing with the web server, and after closing my browser window, turned the wifi back to client mode. Crash and reboot. Log level was set to Info at the time (see next email for more on that...), and thought it was a stack issue, but rather it appears to have hit an illegal instruction. So, perhaps a stack corruption? I don't recall if the modem was on or not. Only happened the one time, but posting here in case someone else sees it. Greg OVMS > wifi mode client gregnet Starting WIFI as a client to gregnet...
