No Route to host #38

Closed drannex42 closed 2 years ago

drannex42 commented 2 years ago

Describe the bug I am running your script ble-scan and I am seeing my device (a OnePlus 5T), and after plugging in the ble-serial -d 94:65:2d:db:d8:c4 to connect it keeps telling me that there is Bluetooth connection failed: [org.bluez.Error.Failed] No route to host. I attempted to try this same thing with getting the characteristic using a deep scan, but I am receiving the same issue.

I'm closing this as I solved the issue, I had enabled an SP interface to start with a compat version of bluez for access to the RFCOMM on another application. (I really should have remembered....)

For anyone else: Just modify your /usr/lib/systemd/system/bluetooth.service and replace your ExecStart line with:

ExecStart=/usr/lib/bluetooth/bluetoothd -d
#ExecStart=/usr/lib/bluetooth/bluetoothd -C
#ExecStartPost=/usr/bin/sdptool add SP
