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

Hi Petter, Yes firmware is working fine on few custom boards and getting error message on few android phones like android v4.4 and 5.0 . I did few testes with nRF_UART application located in SDK and the failing custom board is working fine with the custom firmware and nRF_UART example project is not able to connect with the custom board.

Yes I looked into the sniffer log and getting CRC error in 1 out of 10 advertise packets for the custom board with custom firmware and also with nRF_UART example project.
