An iPhone 4S (ios 9.3.1) will connect as will another Raspberry Pi using bluetoothctl (5.36). The phone that will not connect is a Google Nexus 5x (Android 6.0.1) I'm use nRF Master Control Panel app on both iPhone and Android. The log file from Android is: nRF Master Control Panel, 2016-04-07 No name (00:02:5B:03:E3:E3) V21:34:19.768Connecting to 00:02:5B:03:E3:E3... D21:34:19.777gatt = device.connectGatt(autoConnect = false) D21:34:24.943[Callback] Connection state changed with status: 133 and new state: DISCONNECTED (0) E21:34:24.955Error 133 (0x85): GATT ERROR I21:34:24.969Disconnected D21:34:24.981gatt.close() I've tried adding the patch you suggested above and I still see the same in the phones log file. The error message on the phone is the same as I have had before and has been solved previously by adding 'ControllerMode = le' in main.conf. History of that discussion is at: http://marc.info/?l=linux-bluetooth&m=145505537711496&w=2 Since moving to 5.38 modifying the main.conf no longer seems to fix the issue. >> bluetoothd[2976]: src/device.c:gatt_debug() Primary services found: 2 >> bluetoothd[2976]: src/device.c:gatt_debug() start: 0x0001, end: >> 0x0005, uuid: 00001801-0000-1000-8000-00805f9b34fb >> bluetoothd[2976]: src/device.c:gatt_debug() start: 0x0014, end: >> 0xffff, uuid: 00001800-0000-1000-8000-00805f9b34fb >> bluetoothd[2976]: src/device.c:gatt_debug() Secondary service >> discovery failed.
