Software Updated for our NRF device, now it does not recognize our Bluetooth device. Roll back BLE and desktop version #.

[boxcarcaravan321]

Our software engineer working on this has recently left the company who and he is unavailable to help out. I am very in over my head with this. The software our tester uses updated and now our NRF device will not connect to the receiver. I am hoping that rolling back the software version will solve this. Does anyone have a link for the BLE v3.0.1 app that I could add as an App Source for nRF Connect Desktop v3.11.0?

The nRF Connect Desktop app was originally v3.11.0
The BLE internal app was v3.0.1
The BLE dongle was nRF51. J-Link firmware: J-Link OB-SAM3U128-V2-NordicSemi
Using nrf-device-lib-js version: 0.4.5
Using nrf-device-lib version: 0.11.0
Using nrfjprog DLL version: 10.15.1
Using JLink version: JLink_V7.58b

after the update...

 nRF Connect updated to v3.12.0
The BLE app is v4.0.1

I've tried using multiple different versions of the Connect Desktop app and the BLE app, none of them work with the python tools that our previous Dev created.

Hi,

Can you share some more info on your setup?

If you open the the BLE app and click on the system report, and share. 



As for down grading:

This might work but no guarantee.

Thanks for the visual reference. Here are the two system reports. One with the dev board and the other with the dongle.

So you rolled back to v3.7 and this did not solve the problem ? 


You can download the nRF connect for desktop version here:
https://www.nordicsemi.com/-/media/Software-and-other-downloads/Desktop-software/nRF-Connect-for-Desktop/3-11-0/nrfconnect-setup-3.11.0-ia32.exe 

And v3.0.1 of the BLE app here: 
https://github.com/NordicSemiconductor/pc-nrfconnect-ble/releases/tag/v3.0.1 


find the .nrfconnect-apps\node_modules loaction. for me its C:\Users\me\.nrfconnect-apps\node_modules , then replace the pc-nrfconnect-ble folder with the one you downloaded. You will have to re-name it so that it maches the file you are replacing. So pc-nrfconnect-ble

Then open the nRF connect for Desktop app and open the BLE app. This might work.... not 100% sure. Can end up with a app that is just blank.

Jonathan

Hello Jonathan,

Your concern about the app being blank was correct. Is there a .json link that I could add as an App Source for BLE v3.0.1. I have been searching everywhere I know to and have not found the right link.

Thanks again!

[boxcarcaravan321]

Hi Jonathan,

I was hoping you might have a link to the BLE v3.0.1 app that I can add as an App Source for the nRF Connect Desktop v3.11.0.

Best Regards,
Kyle

Try to uninstall all the apps from the nRF connect for desktop app. Then re-launch the app and update to the newest version. 

Go to SETTINGS and click the Add Sources button, then add this link: 

https://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.11-apps/apps.json 

restart the desktop app, now you should be able to download two versions of apps available, so download the 3.11 compatible app and see if that works. 

Regards,
Jonathan

That still only allows me to install v4.0.0 for the BLE module. I did find a link to download v3.0.1 and it is working now. Thank you for all your help Jonathan.
