nRF52832 disconnecting from android device

To fix this I restarted the 'advertising_start()' service when it got disconnect like so:

case BLE_GAP_EVT_DISCONNECTED:
{
bool erase_bonds;
NRF_LOG_INFO("Disconnected.");
advertising_start(erase_bonds); //added by AUAK
// LED indication will be changed when advertising starts.
// m_conn_handle = BLE_CONN_HANDLE_INVALID; //added by AUAK
break;
}

This restarts the service once it is disconnected.

Sorry for the delayed response. Could you please open a new DevZone ticket please?

I am having a similar problem with my nRF52 using SDK_15.3.0. What happens is the led on my board is blinking and when i connect it stabilizes. But when I disconnect it stays stable (like its still in connection) and the nRF52-Development kit is broadcasting no more and you have to restart it.

Any leads on this?

I'm having a similar problem. I've loaded modified Thingy52 firmware, and I've downloaded the Android app for the Thingy from the GitHub. I'm using a Samsung Tab A running Android 5.1.1.

The Thingy will connect via the release versions of the Thingy app (through both iOS and Android app stores), but after uploading the unmodified GitHub Android code, the Thingy will connect but immediately disconnect, giving me this output on the RTT viewer from the Thingy.

After the disconnect, the Thingy becomes unresponsive and must be restarted.

What might be causing this?

Have you been able to connect your Thingy to your Android tablet using the Nordic Thingy app?

Why are you using the Thingy SDK? Are you using a Nordic Thingy:52? If not, could you download the sdk 14.1.0 from this location?

I would check this devzone post & this one. Also, which SDK, Android version & phone are you using?
