nrf51822 getting disconnected after some time

[Sreekanth]

I am trying to communicate between nrf51822 and Android device using Gatt. But nrf51822 invokes UartService.ACTION_GATT_DISCONNECTED after some time, the disconnection happens in middle of sending of data. Please shed some light on this issue if any one has faced such problems before.

Does it happen every time? What is some time? Are you able to do a sniffer trace and attach it to the question?

After sending of some bytes, the nrf51822 is changing the UART status to UartService.DEVICE_DOES_NOT_SUPPORT_UART

The nRF51822 changes the status? Sounds strange. Could you do a sniffer trace? What is your setup? ble_app_uart on nRF51822 with SoftDevice version ? and SDK version ? What is your central device? Have you made the Android app yourself or is it ours?

I have used your application only, but I am sending more data by looping, at one loop iteration, I am sending 20 bytes using the same function that you have used. mService.writeRXCharacteristic(currentArray); currentArray is the array of bytes with length = 20.

I see. Would it be possible for you to do a sniffer trace with the nRF Sniffer? Maybe it can shed some light on what is happening.
