Proximity application is not working in android smart phone

[balaji]

Hi, How can i test the proximity application with the use of nexus4 smart phone and nrf51822 evaluation board? We already tested the ios proximity application which are all working fine. When we try to test the android application we are facing lot of problem's. For ios we have three application's to test 1.nRF Toolbox, 2. nRF Utility, 3. nRF proximity, but for android 4.3 we have only one application nRF Toolbox, that is also not working. It gives error like, error on connection state change and error on discovering sevices. Is there any other proximity application we can get with the source code?

Regards, Balaji.

Hi Balaji,

Have you updated your Nexus 4 to Android 4.4.2? The update to 4.4.2 (or 4.4.1) from 4.4 will solve the issue with bonding and therefore helps the proximity profile work properly.

You can wait for over the air update for your device, or can follow this instruction to update it manually. Note that the official update might be different.

You might have problem installing the driver for the Nexus 4 when in recovery mode, you can follow this instruction to add the driver manually:

Go to Device manager, select your device and select Update Driver Software -> Browse… -> Let me pick manually from a list… -> Select Android Device and Android Composite ADB Interface from Google

Could you try installing the app from Google Play?

Can be found here.

I installed the application from google play only.

@Balaji: Could you test with the Master Control Panel Android app ? You can find it on Google play as well. You can first start with the Heart Rate Measurement example and let me know at which part you have the error and upload the log file if possible:

• Scan for device
• Select and connect to the heart rate measurement slave
• Read characteristics values
• Enable notification, on battery and HRM
• Disconnect and reconnect

If it works with HRM example, you can move to Proximity example to test.

On our device here the Master Control Panel works fine. There is some issue with the server on the phone with the Toolbox-Proximity app, but you should still be able to connect.
