I am trying to run the v.0.9.90 app on a Redmi Note 2 (MIUI 66.77.33.00).
I can pair my T-Beam with Bluetooth but after that the app says my device is disconnected or sleeping. All text input fields are greyed out and do not receive any input.
f/w: 0.9.3, 1.0 and 1.1.0 (alpha)
T-Beam V1.1 w/ NEO-6M
