hciconfig is not showing my nrf52840 dongle on my linux terminal

SanthoshN

Hi,

I flashed my nrf52840 dongle by nrf Desktop connect app with ble-blinky hex file from nRF5_SDK_15.2.0_9412b96 SDK and I am able to connect to it from nrf connect ios app.

But unable to see the device on hciconfig.

Basing on this below link flashed the dongle with ble_connectivity_s140_usb_hci_pca10059.hex which I got from SDK instead of Zephyr BLE HCI_USB controller firmware as I didn't find its hex file.

devzone.nordicsemi.com/.../flashing-nrf52840-dongle-to-support-bluez

What should be done to make the dongle visible in hciconfig.. ??

    Thanks for the hex

    With this hex I am able to see the device but its mac id is wrong.

    I belive there is a HCI command to set the address, please refer to the Zephyr documentation for more details.

    I am trying to change the address with bdaddr but it is throwing the following error

    pi@raspberrypi:~/bluez-5.50/tools $ sudo ./bdaddr

    Can you suggest me how to change the BD address and make it work on my raspberrypi

    I upgraded the kernel and tried to change the BD address

    It is not updated and throwing the following error

    pi@raspberrypi:~/bluez-5.50/tools $ sudo ./bdaddr -r 00:19:1D:6D:D9:DA
    Manufacturer:   not assigned (1521)
    Device address: 00:00:00:00:00:00 (XEROX CORPORATION)

    Unsupported manufacturer
