NRF Connect not seeing my NRF52840 dongle

[CA Hinton]

I installed NRF Connect, the BLE plugin, and successfully flashed the dongle firmware. IIn NRF connect, the BLE plugin scan button is disabled.  'Quick Start' was unable to see the device and suggested raising a ticket.
I *think* this may be because the dongle is running...

Hi,

Thanks for reaching out. I think this issue is most likely due to the J-Link version mismatch. So can you downgrade your SEGGER J-Link installation to v9.24a, which you can download from the SEGGER J-Link Software page (https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack), and then retry connecting your dongle.

Best Regards,

Hi Sayed, Thanks for the prompt reply! I installed J-Link version 9.24a (JLink_MacOSX_V924a_arm64.pkg) and now the BLE tool identifies the device when I press select. However, there is the next problem. I don't see JLINKARM_DLL in bundle, and I got a notification about deprecated intel support,

Regards

Quick follow up - I downloaded the universal installer and seem to be past configuration problems. Now it's data_integrity:0 err_code:0x802c

Hi,

Okay thanks for a follow up. The log confirms the J-Link side is now sorted. The universal installer was the right call and regarding your new error can you confirm you have connectivity firmware on the dongle.

You can check by pressing the RESET button, once in bootloader mode then program it.

i,

Thanks for reaching out. I think this issue is most likely due to the J-Link version mismatch. So can you downgrade your SEGGER J-Link installation to v9.24a, which you can download from the SEGGER J-Link Software page (https://www.segger.com/downloads/jlink/#J-LinkSoftwareAndDocumentationPack), and then retry connecting your dongle.

Best Regards,

Hello, I'm also encountering the same problem. I've plugged the NRF52840 dongle into my computer's USB port, but there's still no response. My Device Manager doesn't show any devices listed. I've already installed J-Link 9.24.
