I posted this problem a while ago, but never received a working solution. I am using Solex v1.4.7. Solex works fine with 1st vehicle, but cannot detect the 2nd vehicle. I've rebooted the tablet, drone, controller, changed WiFi SSID, etc. For whatever reason, the 3DR solo app detects my 2nd vehicle just fine, but Solex will not. On the main Solex screen where it shows which WiFi it's connected to, it shows the correct SoloLink_<xxxxx> WiFi that I'm connected to, but can't detect the vehicle for some reason !!! It's very frustrating !!! I'm about to delete my first vehicle and see if that will resolve it, but I don't want to loose all them statistics on the 1st vehicle. It would totally suck if Solex cannot support more than 1 vehicle at a time!
