Hi all I would like to implement something new in the profile (Bluez 5.52) So I'm testing how it works first. A. btgatt-server test I ran btgatt-server on pc and ble scanner app on mobile. I can see the heart rate service in the ble scanner and read / write. it works well!!! But... B. bluez/profile test The tests were performed in the following order. 1.sudo ./bluetoothd --plugin=deviceinfo -nEd 2. run the hciconfig command $ sudo hciconfig hci0 up $ sudo hciconfig hci0 noleadv $ sudo hciconfig hci0 noscan $ sudo hciconfig hci0 pscan $ sudo hciconfig hci0 leadv In the ble scanner of mobile, other services except 0x1800 and 0x1801 are not visible. Even if I change --plugin = xx, the service does not appear in the ble scanner. Not even in btgatt-client. gatt_db_service_get_claimed () has also been modified, but it does not work. Please guide me how to test bluez / profile. thanks. best regards.!
