User reviews

V6.0 won’t reconnect

Jarring update hides presets and refuses to reconnect to NUS Nordic Uart Service if device disconnects requiring app restart. Please fix the reconnect bug. Even manually reselecting device leaves stuck stale state. Way more clicks required to get to loaded presets, not shown by default when configured, hidden under all messages. I do like rapid switching between presets. Maybe needs a presets keyboard to better use screen space and allow more presets. Please fix reconnect as i cant roll back this auto update.
