nrf51822 android uart service disconnect

[sowmya]

Hello,

We are working on android UART service and NUS characteristic to receive notification and testing with the custom board with S130 stack acting as a peripheral. We are facing issue in connection with peripheral after connect, we are getting service null and displaying the message Device does not support UART, disconnect on the phone application.

We tried with S110 peripheral UART service application, but no success. But the same application is working with few boards. Can anyone tell me, are we missing any configuration in the android application?

Regards,
Sowmya

If the unmodified ble_app_uart works on your custom boards, I don't think the problem is with the Android application, but more likely with the modified firmware. Exacly what the problem is difficult to pinpoint. A sniffer trace of the connection (not advertising) would be helpful. Or maybe you can upload your complete project so I can test it here? Please let me know what SDK and SoftDevice I should use. If it is project is private you can add a case on your MyPage at nordicsemi.com, and we can handle it there.
