#obx_server
obex over L2CAP bluetooth. server uses IOBluetooth. python client tested on rasberry pi.
macOS <-> raspberry pi file transfer.
mac requirements: macOS (tested on 10.15.7) xcode (author used 11.7)
pi requirements: a model with bluetooth python 3.x pybluez
compile obx_server with xcode (maybe need change build settings such as install owner). ensure devices are near each other switch bluetooth on (mac and pi) no need to pair but might get connection-request-pop-up.
modify obxget.py line 7: MACADDR = "AA:BB:CC:DD:EE:FF" so that the bd_addr is that of your mac obxget.py needs obx_const.py
you can find nearby devices using hcitool on pi. to find your mac's bdaddr do: hcitool scan in the raspberry pi terminal. bluetoothctl can also be used to find bt devices.
you may need to change some settings on the mac: firewall, file sharing, bluetooth sharing run obx_server when you see service L2CAP chan psm = 0x1001 do python obxget.py <filename_to_get> at the raspberry end. a pop-up might appear, asking permission to access a directory.
note this is a rudimentary obex ftp that does not comply with the SIG standard.
