Thankyou

I just wanted to take the time to say thank you for the app you have made and the help that you give. I have been under a lot of pressure lately and this is my first time dealing with technology in this way. I haven’t fully grasped everything about usage yet, but this app has opened my mind to a whole new world of possibilities and understanding. Thank you for your continued effort, patience, and improvements made during such times as these. I appreciate you, and look forward to better understanding the wonderful information you provide. I am probably a century behind on my understanding of technology (maybe even a lifetime). I feel immense pressure, and things have been very overwhelming, but I am relentlessly absorbing new information daily, in attempts to grasp and understand enough so that I may know what to do with it. There’s a learning curve for sure, but I’m all in on wanting to understand, and I won’t give up until I succeed in that, so that I may be able to make decisive moves that generate positive outcomes. Thanks for providing help and tools that assist me in getting there. May today bring progress and blessing.

Sincerely,
Nathan

Can't read data from Bluetooth device

Bug

Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good

Bug

Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).

Bug

Cant go past the initial announcement. The app is unresponsive to the taps.
