Will there be an Android 4.3 app download for the Proximity Profile?

Eliot Stock

I'm implementing an Android 4.3 app which uses an nRF51822 and the BLE proximity profile. I have the following as starting points for the app code:

  1. The BLE sample app in the Android SDK. This can see the device on a scan and seems to connect, but then immediately loses the connection.

  2. The nRFTemp app download from Nordic. Obviously this doesn't use the proximity profile, it's for the temperature sensor.

Am I better off debugging the dropped connection on 1, or adding the proximity profile services to 2? Nordic people, are there any plans to release a sample app download for the proximity profile?

    Hi Eliot,

    As you can find with the BLE sample app in Android SDK, there is an issue with Android 4.3 devices from Google(Nexus 4, Nexus 7) that the reconnecting after bonding is not performed properly. We are suspecting that it's the issue with the driver/stack on Nexus devices. The issue doesn't occurs on Samsung device running Android 4.3 (same API).

    Currently we are working on porting the nRF Utility app to Android 4.3. But I have no idea when will it be available.

    My suggestion for you in the mean time is to try with Samsung devices (S4 Google edition, or Note 3) and develop your application base on the BLE sample app.

    We will very soon release a new app that pretty similar to the BLE sample app from Google with added features, please stay tune.

    Thanks. I'm actually using a Galaxy Nexus (the Nexus model before the Nexus 4) which out of the box doesn't have BLE enabled, but on which it's possible to enable BLE if you've oem unlocked and rooted the device. I think it's subject to the same problems in the Bluedroid stack as you mentioned, but I've been able to work around them by stopping the adapter and restarting it occasionally. Here's hoping all that is fixed in Android 4.4.

    Looking forward to this new app from Nordic. I guess I'll get a notification email for that when released, since I have the nRF51822 dev kit in my products on "My Page".
