This app is intended to upgrade the firmware of some Elite indoor trainers. The app automatically checks if there’s an available firmware and, if the user confirms, it proceeds with the update. Tips / troubleshooting: - Be sure that the trainer is powered and the blue led is blinking. - Keep the device close to the trainer to improve the transmission - Close the all the app using Bluetooth in background (my E-training, Zwift, TrainerRoad, The Sufferfest, etc…) - If you have problem in the connection, try rebooting the phone/tablet and the trainer. If this doesn’t fix the problem, contact us at myetraining@elite-it.com
