I've Openwrt running with all the needed packages to support my USB bluetooth dongle. Openwrt finds the dongle and finds the device that it needs to connect to. So far so good.
The problem is that I cannot figure out how to provide the fixed pincode during the pairing of the two devices. Most examples are based on older versions of Bluez. The tutorial on: https://wiki.openwrt.org/doc/howto/usb.bluetooth seems to be based on Bluez4
Normally Bluez5 comes with bluetoothctl to guide the pairing process and generation of the required configuration files, but this tool seems to be missing in the bluez-utils 5.1.3 package.
I've managed to connect both devices with the same BT-hardware on a different Linux based platform, but with the help of bluetoothctl.
How can I pair the two devices without bluetoothctl? If bluetoothctl is needed, how can it be installed?
