It seems the nRF52 (peripheral/slave) disconnects in packet 1802. Are you calling sd_ble_gap_disconnect() anywhere? I also see that the RPi3 (central/master) doesn't respond to the Find By Type Value Request sent by the nRF52 in packet 950. So I'm guessing that you are calling sd_ble_gap_disconnect() when you get the BLE_GATTC_EVT_TIMEOUT event, see this.

Ok. So unmodified ble_app_uart works? What is BLE manager?

I had a look at the traces. It seems the slave(nRF52) is sending a Find By Type Value request. I'm not sure why, but there doesn't seem to be a response. This should not cause a disconnect after 30 seconds, but it should give a timeout event. Could you upload the hex file with application you are running? So I can test it here.

Thank you for the traces and the update. Please try to answer my other questions as well.

Please post the sniffer trace file, not picture. You can edit your question and add it there. What SoftDevice and SDK version are you using? Are you using the unmodifed ble_app_uart example? Did you run this example on the nRF51 as well? Do other examples work on the nRF52?

I'm using the uart over ble example from nordic. here are the sniff results! i think perhaps gatttool need the uuid in the advertisement. I testet with some other Ble devices and every device which worked they advertise there uuids! I will test it!

Difficult to say. What application are you running on the nRF52? Could you do a sniffer trace of what is happening on air? You can use the nRF Sniffer.
