nRF Connect Does Not Offer to Update Connectivity Firmware

[Marciano-PL]

Software version: nRF Connect v2.6.2
Hardware version: nRF6825 Rev. 1.1.0 (PCA10031)
Hardware version: nRF52840-Preview-DK  Rev 0.9.3 (PCA10056)
SDK version: nRF5 SDK v12.0.0
SDK version: nRF52 SDK

I have tried with both an nRF51 Dongle, and nRF52840-Preview-DK. When using the Bluetooth Low Energy app in nRF Connect and select my device the response I get in the log is:

16:35:48.336     Application data folder: C:\Users\TAH\AppData\Roaming\nrfconnect\pc-nrfconnect-ble

16:35:53.942.    Validating connectivity firmware for device with serial number 000680689476...

16:35:55.703.    Error while setting up device 000680689476: Opening COM4: File not found

16:35:55.706.    Device closed.

It does not offer me the option to upload the connectivity firmware to the device. I have tried numerous times, and cannot find the firmware myself for my device. I have found the ble_connectivity example for the pca10040 device, but I am hesitant to use it on mine as it is a different device altogether. How can I get my Dongle or DK up and running and performing DFU's to my Thingy52?

Hi, 

Can you do a nrfjprog -e in CMD and open the Bluetooth Low Energy Application and click yes on the pop up which asks if you want to program the device?

Click yes on this window.

Hello Amanda,

I followed your instructions and received no pop-up. I even selected my device (dongle) and got the same behavior as before. Am going to update the nRF Connect app to v2.7.0. Will report back.

Edit:
I updated to v2.7.0. I closed the app, ran "$ nrfjprog -e" and reopened Connect. I received a the same error again:

Hi, 

v2.7.0 needs J-link v6.44e. Please check and update the J-link firmware version, and then repeat the steps again.

Hello,

I installed J-link from the link you provided. It calls itself v6.44g though. Is that a problem?

After installing I restarted my PC and reopened nRF Connect to receive the same error as before. However, this time when connecting my nRF52840 DK board, I received this pop-up.

Hi, 

The link should be https://www.segger.com/downloads/jlink/JLink_Windows_V644e.exe. 

If it still cannot work, I would suggest revert to nRF Connect for Desktop https://devzone.nordicsemi.com/cfs-file/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-f04f0de7850e40f080f8b53e06b0bc54/nrfconnectsetup260.exe + J-Link v6.22 ( https://www.segger.com/downloads/jlink/JLink_Windows_V622.exe ).

Please let me know that can help or not.

Hi,

I tried all of these solutions, and none of them seemed to change anything. I think that the nRF Connect for Desktop application doesn't include the required .hex files for the connectivity firmware. I've searched all through the program files and haven't found anything resembling the firmware file required.

Edit: I have searched the web far and wide for this connectivity firmware and cannot find a .hex file anywhere. I found a GitHub repo for compiling it myself, but I am not familiar enough with CMAKE to get it work, among other problems. Can I just get the connectivity firmware hex? That's all I need to get on with my project.

Hi, 

You can find them under <nRF5_SDK_15.3.0>\examples\connectivity\ble_connectivity\hex

I have now tried uploading each of the pca100056 hex files onto my nRF52840 DK and tried them with the nRF Connect BLE App, yet I still get the exact same error message.

Hi, 

The only thing I can think of is that the firmware on the debugger-bridge is incompatible with windows for some reason. Could you try the following steps, and see if the CDC driver is successfully loaded?

1. Uninstall all Segger JLink installations

2. Remove the "JLink CDC UART Port" device, and check to delete the driver when this window pops up.

3. Power off your nRF-DK, hold in the "IF BOOT/RESET", then power it back up. Now it should show up as "BOOTLOADER".

4. Download one of the older JLink firmware https://www.nordicsemi.com/Software-and-Tools/Development-Kits/nRF52840-DK/Download#infotabs (The "Interface MCU Firmware" image is the first file.), and copy the .bin file over to the MassStorageDevice named "BOOTLOADER"

5. Install a version of the JLink from this site (the 6.44e for 2.7.0/ 6.22 for 2.6.0), click "older versions" to see the list.
