So I have the open app working on my leaf. But lately I've noticed the app seems to keep losing connection to the car. When I go close to the car I can log on via wifi and the module is working. Is this expected behavior? Can I make my own local server for the car to log into?
Check the server v2, wifi and cellular confituration and status. Especially the auto-start settings to make sure they all are configured to start automatically.
The 'module summary' command will give you a nice summary, but also each component has a 'status' command (server v2 status, cellular status, network status, wifi status, etc). Those will tell you what is going on.
