https://devzone.nordicsemi.com/f/nordic-q-a/9484/nrf51822-getting-disconnected-after-some-timeI 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 oneen-USTelligent Community 13Wed, 30 Sep 2015 11:15:41 GMThttps://devzone.nordicsemi.com/thread/35020?ContentTypeID=1Wed, 30 Sep 2015 11:15:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a01c061d-3d14-44b2-b047-b1251952cc6dPetter Myhre<p>Thank you for sharing.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35019?ContentTypeID=1Wed, 30 Sep 2015 07:42:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:341f4b96-3b0b-4256-9f9d-27380e3bdde6Sreekanth<p>Hi Petter Myhre, it was a problem at the android end, there was a bufferoverflowexception in android while trying to send data. If it will help some one, adding sdk.build.tools=18.1.1 to project.properties have solved my issue.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35018?ContentTypeID=1Wed, 30 Sep 2015 07:31:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b1863901-4045-4a79-9b3b-7d1e8f20266aPetter Myhre<p>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.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35017?ContentTypeID=1Tue, 29 Sep 2015 12:08:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9197ae06-6fae-40ed-ac55-14796bf4602aSreekanth<p>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.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35016?ContentTypeID=1Tue, 29 Sep 2015 12:02:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a1a8eb0e-5b65-4242-bdcf-41cb7d3fde7cPetter Myhre<p>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?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35015?ContentTypeID=1Tue, 29 Sep 2015 11:37:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6dc24a62-47f7-491c-97f3-8afd2be0029aSreekanth<p>After sending of some bytes, the nrf51822 is changing the UART status to UartService.DEVICE_DOES_NOT_SUPPORT_UART</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/35014?ContentTypeID=1Tue, 29 Sep 2015 09:18:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6a1a3842-26bf-48a8-822f-34959c7a4770Petter Myhre<p>Does it happen every time?
