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.

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

Any help is highly appreciated

nRF connect desktop uses serialized softdevice (Nordic BT stack) API to communicate with the connectivity chip, not HCI commands. In other words, ble_connectivity_s140_usb_hci_pca10059.hex will not work with the Bluez host. 

Do you have a programmer to program the dongle, or do you need to upload the FW through USB DFU? 

[Vidar Berg]

Zephyr does not include any pre-compiled .hex files so the samples need to be built from source. I have built the example for you, but not verified if it works, see attached. 

zephyr.hex

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

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

[SanthoshN]

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

Could you please reply on this.

I'm stuck at this point
