Slypod Pro upgrade needs to be connected to the power cord to make it in a charging state.
And please note that the distance between the phone and Slypod Pro should not exceed 30cm during the upgrade process. The IOS upgrade time is about 3-4 minutes, and the Android upgrade time is about 8-10 minutes.
If the upgrade fails, please plug in the power cord and repeat the upgrade until it succeeds.
Do not perform any other operations during the upgrade process. At the same time, keep the App in the upgrade interface, and do not turn off the screen or lock the screen to avoid failure to send upgrade data!
