simcom 7600 board not responding
by Derek Caudwell 05 Jul '23

After restoring my main unit with a full reflash via usb I have lost communication with the 7600. The 7600 itself seems to be fine as I can connect via usb and send/receive AT commands. Before I look at the hardware rx/tx lines to see if there is anything being transmitted between the two boards I thought it might be sensible to reset the 7600 with AT+CRESET. I take it there are no custom settings and a reset will be fine? Any other suggestions on diagnosing the problem? I also noticed the PoweringOn and PoweringOff pulses do not match the specification sheet in the current code base, with a typical pulse of 500ms to turn "on" and min pulse of 2500ms to turn "off". Once I get my unit working again I will test and submit a PR. Many thanks

Compiling OVMS under WSL!
by Michael Geddes 04 Jul '23

Hi all, I should probably have documented this closer so that we could include it in the instructions, though it's essentially the same as the Linux ones. That being said, I can confirm that Ubuntu running under WSL will happily compile OVMS! WSL 2 under WIndows 11 seems to somewhat cope with X11/Wayland and with sound (sometimes laggy), so I can use the X versions of git gui and gitk... Unfortunately the responsiveness of gvim is not great (some weird lag in the keyboard input) but using wsl as the shell in windows gvim works quite well! I've got a ovms.vim that sets things up. It seems VSCode using WSL is a possibility as well: https://code.visualstudio.com/docs/remote/wsl imho I think this would be much nicer than dealing with mingw. //.ichael

Feedback on P/R for passing state as parameter
by Michael Geddes 03 Jul '23

Hi all, I have this p/r from a few weeks ago that I'm hoping to get moving forward with so that I can put forward some other less mundane requests. This is part 1 of a few that removes polling state information from being accessed from OvmsVehicle. https://github.com/openvehicles/Open-Vehicle-Monitoring-System-3/pull/914 //.ichael
