I am going in circles trying to get this scanner working...so I'll post my steps , in case there is something I've overlooked!
The scanner works fine in windows10 Bluetooth in serial spp mode (terminal shows scan number codes)
Windows10 has been unpaired, so as to not potentially interfere with the rpi connection.
RPI4 with Stretch. Using cutecom serial terminal. Need to scan barcode numbers & see them in the terminal
Connect by bluetooth SPP.
1) All latest RPI updates have been applied
2) All rpi prefernces turned on , including serial port & serial console.
3) Edited /.../bluez.service to include
ExecStart=/usr/lib/bluetooth/bluetoothd -C
ExecStartPost=/usr/bin/sdptool add SP
4)rebooted rpi
5)Under blootooth icon scanner shows up as :
BarCode Scanner spp
6) select above & Hit PAIR...waits a second , then replies: Paired Successfully, but this device has no services which can be used with the raspberry pi !!!!!
Have I overlooked something? Something else needed installed/configured?
After many hours, this is quite aggravating!
If I config the scanner to HID mode, it can pair (pair with: scanner HID) to the rpi & scans show up in a command window (not serial terminal)....so the scanner & BT itself seem functional.
