When I got my P2V+ last week and flew right out of the box with no problem. But the next day for the 2nd flight, I could not able to have my iPhone 5 to connect to my P2V+. The Range Extender's battery is fully charge with green light on. When I select Phantom_XXXX from WiFI network list, the error message on iPhone says "Unable to join to the network" and then it was not on the WiFi list anymore even my iPhone is not connect to any other WiFi. I tried with my iPad but still no luck. Do you think Range Extender is defective? I got email from DJI and saying they do not have the trouble shooting steps at this time yet and suggest to wait for the new App upgrade but I do not think App was not the problem. Does anyone had this problem before? Any input would be appreciated.
