Trying to see DongleBLE in linux with NCS

[Piwy]

Hello,

I want to see my dongle BLE with command lsusb with NCS. I succed to see it with a FTDI USB to UART but i want to succed with only USB.

I succed only USB just with the old SDK connectivity by using a patch whitch came from pc-ble-driver. I tried to developp a pc-ble-driver version NCS with shell command but for commercialisation i can't have a FTDI on my board. can you help me ?

I use for my tests a dongle BLE nrf52840.

Regards,

Hi thanks you, it works with Dongle BLE, but i have always one issue.

Like i saied i try my code with dongle BLE and it's work. But i have a custom dongle that don't include reset button and then don't include also the open bootloarder. I can't see my cuistom device.

The only difference beetween them is the open bootloader that is in the Dongle BLE, do you know how to include it in my code to have the programme ? i need tio include in it because i don't know why i can't access with programmer to my custom board....

The nRF5 open usb bootloader requires a button, as described here: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v17.1.0%2Flib_dfu_trigger_usb.html

 

You'll need to program your custom dongle using a dedicated SWD programmer, for instance a jlink debugger.

 

Kind regards,

No i don't see it with lsusb or his fiel descriptor like for the Dongle BLE but i can flash it. I can programme it with jlink. But the same soft in the dongle BLE don't work with my custom dongle, the only difference as i say is the nrf5 open bootloader, the HW is pretty the same... I don't understand why i can't see it.

I tried to use MCUBOOTLOADER. but it was really complicated to use it with my config...and it helps to see the device with lsusb and have a file descriptor but it locked command... I really don't understand how it works

Hi,

 

As you do not share any log output or debug information, it is very hard for me to state what is wrong.

Which board are you configuring for? If if is the nrf52840dongle_nrf52840, it has default flash offset to accommodate the bootloader, as shown here:

https://github.com/nrfconnect/sdk-zephyr/blob/v3.1.99-ncs1/boards/arm/nrf52840dongle_nrf52840/Kconfig.defconfig#L24

 

If you do not have the bootloader present, you can set "CONFIG_BOARD_HAS_NRF5_BOOTLOADER=n"

 

Kind regards,

Håkon

I don't have log to shwo unfortunatly...

I just can say that my soft zephyr work with the dongle BLE because of his open bootloader (i think so), but we can't access to it unfortunatly...

With Donle BLE Nordic, i can acess to the dongle and send shell command

For a custom dongle with the same HW as the dongle BLE nordic, i firt try to put my soft into it with programmer(nrf descktop) but i can't acess or just see my device in linux contrary to the Dongle BLE nordic

The only difference beetween them is this open bootloader DFU.

Then i tried to use an open bootloader from old sdk (bootloaderNRF5 : nRF52840 Dongle Programming Tutorial ) , with this open bootloader i can see my device in linux but i can't send shell comand anymore, tthe device show nothing (no log...)

Do you know how the soft from reset button from the dongle BLE nordic works ?

I use the nrf52840dongle_nrf52840 for both all theses set-up.
