What phone are you using? Did you try any other?

cinny007 commented 4 years ago

Redmi MI A3, Redmi note 4, Samsung M30....It's happening in all devices.

I tried on SAMSUNG Galaxy Tab S3 Android 8.0.0 and SAMSUNG Galaxy Note4 Android 6.0.1. Both phones are the same. The log is a Samsung Galaxy Tab S3.

After error 129, connecting to nRF Connect for Android, and Enable glucose measurement notifications and record access control point indications. In this state, go to the nRF Toolbox and connect with the device. Pressing the All button will download the data but will not display anything on the screen. Attach the log. Log 2020-02-17 174232.txt This is also the same for both phones.

@philips77 Did you check?

philips77 commented 4 years ago

Hi, I'm on it right now. Sorry, I was busy with other tasks. I managed to reproduce the issue, will investigate it now.

philips77 commented 4 years ago

Ok, I found the issue. The Glucose Measurement characteristic notifications were not enabled. Instead, the app was enabling Glucose Measurement Context characteristic notifications twice. The fix is on its way.

Working fine now. Thanks @philips77 . I actually found one more issue for the same device. While inserting the strip in the accu-chek device, the application disconnects with the accu-chek device and hence I am not able to take the current reading. Shall I create one more issue for that?

philips77 commented 4 years ago

Yes, please create a new issue.
