You can do it by finding recent updates in App Store if you've got an iPhone or Google Play if you use an Android smartphone. Once your App update completed, get your eVscope up and running. This will trigger your eVscope's software update automatically and will take approximately 15-30 seconds. The App version can be seen in the Store as well.
1) start your eVscope (red button ON)
2) get connected (Wi-Fi)
3) launch your App
4) launch the update (it will ask you to)
Keep your scope ON during that time and stay close. Please isolate it from other Wi-Fi devices as they can interfere. If it does not work within 2-3 minutes, abort it and restart your App. You can also restart your phone and eVscope. You may want to try with another phone as well.
Now you are done. Enjoy your observation!
