Android BLE Notifications

Dialog Smartbond Bluetooth Low Energy – Software

Hello,

I am using DA14580 in my design and I am able to connect with Reference Source Code provided by Android Studio.

However, when I am trying to enable notifications, I get data for 7 sample readings and then the notifications stop.

I have to enable notificaitons again, to get data. And this time, I don't have any problems.

I am clueless to what the problem is. Any suggestions on what I might be doing wrong?

Do you have any reference code to get started?

Pairing Failed with the device which sets LinkKey bit at LE Key Distribution on Pairing Request.

Hi,

When DA14583 connects to Xperia Android 6.0 device, we got "Pairing Failed" from DA14583.

这个问题似乎与LinkKey bit at LE Key Distribution on Pairing Request. This bit is added in Bluetooth Core Spec. Version 4.2, and it was reserved bit in 4.0 and 4.0.
When we tested Pairing sequence using Nexus 6 (android 6.0), the pairing worked well because Nexus 6 doesn't use LinkKey bit. (I believe Xperia's implements is right. Because Xperia expose it use version 4.2.)
