(this is the reason you had to enable pscan to make it connect). To workaround this: tools/btmgmt power off tools/btmgmt bredr off tools/btmgmt power on Unpair device on Android phone and toggle BT off/on on the phone. After that it should work OK. Also please DONT'T use hcitool for enabling advertising. Use advertisement API (just start ./test/example-advertisement) Not having registered GATT services over BR/EDR is something we need to work on (or disable GATT over BR/EDR). > Best Regards, > Tak > > > 2016-04-08 11:54 GMT+09:00 Hyuntak Lee : > >> Hi Luiz, > >> > >> 2016-04-07 21:17 GMT+09:00 Luiz Augusto von Dentz : > >>> Hi Tak, > >>> > >>> On Thu, Apr 7, 2016 at 2:20 PM, Hyuntak Lee wrote: > >>>> Dears, > >>>> > >>>> I am testing a gatt server with iphone and android. > >>>> iPhone is working nicely, but unfortunately andorid cannot retrive > >>>> registered GATT services. > >>>> I tested with a bluez-5.39/test/example-gatt-server file. > >>>> Can you advice me? > >>>> > >>>> My step is below: > >>>> > >>>> * Peripheral env > >>>> ** Bluez 5.39 > >>>> ** Linux Kernel 3.18 > >>>> ** BT Dongle: NEXT-204BT(CSR 4.0) > >>>> > >>>> * Central env > >>>> ** Android 5.1.1 and iOS 9.3.1 > >>>> ** Test app: nRF MCP > >>>> > >>>> * Build configure > >>>> ./configure --prefix=/usr \ > >>>> > >>>> --sysconfdir=/etc \ > >>>> --localstatedir=/var \ > >>>> --enable-library \ > >>>> --enable-experimental \ > >>>> --disable-systemd > >>>> > >>>> * STEP > >>>> 1.
