EV-BW833 board not recognised by nrf connect Desktop v3.3.0

[Anarchira]

I have a nrf52833 pca10100 which can connect to nRF Connect Desktop to program fine. EVBW833 should have the same chip DK but it is not being recognized. Is there a way I can make nRF Connect do so?

Hi

I'm not able to find any data on a board called EV-BW833. Is this an evaluation/development kit with its own onboard debugger? What error do you get in nRFConnect? Have you tried using the debugger on the DK to program the chip on the EV-BW833? 

Best regards,

Simon

It is an evaluation board. link to board: https://www.fanstel.com/buy/ev-bt832f-evaluation-board-for-bt832f-9xae6-ka33r 

I have already tried using nrf52833 dk to program evbw833, which works. The hex used here was generated using zephyr for board nrf52833. But we would like to only use evbw833 if possible. In theory it should work since it has the same chip as nrf52833. 

Error was unable to recognize device as JLink or Nordic.

Hi

I don't see an onboard debugger on this board, which is likely why the computer can't recognize the device as a JLink, and why you can't connect it to nRFConnect. You'll need a JLink device in order to flash anything onto the onboard chip and this would also be why it's not able to communicate with the nRFConnect app.

Best regards,

Is there a way for nrfConnect to recognize it (maybe not as debugger but some board).

Hi

The alternative would be to have an open USB bootloader flashed onto the device which allows it to be programmed without the need of a debugger. I'm not sure whether this board supports USB like this, but it's worth a shot I guess. You can check out our Dongle programming tutorial for a brief explanation and things to be aware of with the USB bootloader. The USB bootloader example can be downloaded from our Infocenter in SDK v.16.0.0.
