But the nRF UART v2.0 application on my android phone, quits instantly after connecting the ble service with the error message: &quot;Device doesn&#39;t supporten-USTelligent Community 13Mon, 14 Dec 2015 10:20:20 GMThttps://devzone.nordicsemi.com/thread/40515?ContentTypeID=1Mon, 14 Dec 2015 10:20:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:303e170d-2ca2-4c98-8dfc-df7c73888b53Johannes Lorenz<p>Next attempt, I upgraded again to nRF52 SDK-0.9.2 and now the example is also working again.
