I have just sent you an email with:
I have attempted over the last six months to upgrade the firmware on my 6 Dev Beacons with no success
I have both an up to date Android Samsung C5 phone and Apple 6 S, both have your app, and the firmware upgrade sticks at 10% when trying to upgrade from version 4.8.0 to 4.11.0. I have not had any time to do any R&D using your beacons until now and I am now looking to get into using them, providing I can get everything up to date.
On another topic, any hints on getting going in a Windows 10 environment with Visual Studio as my development platform would be much appreciated.
Take care and have a great weekend.
