Yes, I can communicate to my BLE device via eBeacon - it works flawlessly
Fixed it. Extremely weird bug:
When Location is Disabled for iOS app I can’t connect to my BLE Device.
When Location is Enabled for iOS app I can connect to my BLE Device only when I close eBeacon or similar software.
But I can connect to BLE Device via UUID when Location is Disabled for iOS app or I have eBeacon or similar software running in background.
