I've uploaded the FW to the other thread: https://devzone.nordicsemi.com/f/nordic-q-a/43087/hciconfig-is-not-showing-my-nrf52840-dongle-on-my-linux-terminal

There are some python examples included in the Bluez package that you can try: http://www.bluez.org/

How can I use nRF52840 dongle on BeagleBone Black by Python API/commands. Like sending a python command to scan devices or to connect to a device etc.

Hi,

That is correct, the dongle must be programmed with the Zephyr BLE HCI_USB controller firmware (build from latest stable release).

The dongle comes pre-programmed with a serial bootloader enabling .hex files to be programmed through Programmer app in nRF connect desktop. Only requirement is that the FW starts at address 0x1000 in flash and 0x20000008 in RAM as the addresses below are reserved by the pre-programmed master boot record (MBR). That said, I'm not that familiar with the zephyr build system, so not sure how easy it is to change the linker configuration. I think it might be easier to just compile the example as is, and use an external debugger to upload the FW to the dongle.
