Issue when Programming

[YDe]

Hello,

I bought 2x nRF52840 and I used the "nRF Connect for Desktop v3.11.1 to program them.  Unfortunately, after clicking on the "Write" button, the programmer reach correctly the 100% of the programming but then, it stopped with an error.  The problem now is that I cannot use them anymore since they seem not working anymore:.

Could you tell me how to recover them?  Is there any tool available to "reprogram" them with the original firmware? 

Thanks in advance for your help.

Hi,

What are you trying to program and to which device?

Have you tried programming both devices? Does the error during programming occur only on one device or on both devices?

Best regards,

I tried to program the boards for BLE sniffer ("sniffer_nrf52840dongle_nrf2840_4.1.0.hex").  Indeed, the same error appeared while programming each of the devices.  Both of them seems not operating anymore.
Kind regards,

Hi gentleman.  We can close this ticket because the error "Failed to write: Error:Timeout waiting for device xxxxxxxxx to be attached and enumerated" that pops-up after writing the file is confusing but is normal since after programming, the dongle is not anymore in "bootlogger" mode.  Reaching 100% indicates that the firmware is well written in the dongle...

This ticket can then be closed, I guess.

Hi,

Have you selected the device from the upper left corner in your image?

Which sniffer hex file are you trying to program and to which board? Is this one of the hex files provided by us?

Best regards,

Hi,

You can close the ticket if you considered the issue to be resolved.

Yes.  First you need to RESET the dongle, then select the device in the list, load the file "sniffer_nrf52840dongle_nrf522840_7cc811.hex" and click on "write".  As said the error message was quite confusing but seems to be normal.  I then tested the sniffer on Wireshark with success.

Just a side question: does Nordic have a "Wideband" receiver that can explore the complete 2.4GHz band?

Hi,

No, we do not have such a receiver.
