What to do if firmware keeps uploading every time?

• First, make sure you are running the latest version of the SmartPlane app. Currently this is 3.3.0. (To check the app version you have installed, open the SmartPlane app, swipe down the "searching" screen and then swipe the horizon screen to the right. The Software version is displayed in the green bar).
• The issue seems to happen mostly for iPhone 6 and iPhone 6+ users.

Things to try meanwhile:

• Completely erase the app and download it again. You can erase the app by tapping and holding its icon until it starts to jiggle and a cross appears on its top left corner. Tap the cross to delete the app. Then download it again from the App Store.
• Go to Settings app on your iPhone, then choose General > Reset > Erase Network Settings. This is known to solve Bluetooth related problems (although you will have to re-enter your WiFi passwords).
• Try to fully charge your plane.

More information:

• The firmware upload will only happen once and takes around 3 min. If it happens every time, it means the last upload did not succeed and the app is trying again.
• Does the propeller of your SmartPlane rotate briefly (half a second) when you turn it on? This means it is still in factory test mode and the firmware is not yet uploaded.
• If you touch the screen while firmware upload is in progress, you will get a popup box with the Batch No. of your plane. Please include this when writing to us.
