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.

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.

Jonathan

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

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!

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

Also... The nRF connect is used to connect a Bluetooth device (either the dongle or the dev board) to an accelerometer. A custom made python app is used for logging data. There are no error messages. The accelerometer is not recognized by the BLE app.

It looks like we need the BLE app that’s compatible with nRF desktop version 3.11.0. I believe the BLE app that worked for us was v3.0.1.

Thank you for your help!

Thanks for the details, don't see anything that is out of the ordinary so cant point to a issue.

You can try to follow these steps to downgrade the nRF Connect for Desktop app.

You can downgrade nRF Connect for Desktop using the following steps:

Download the latest 3.7 version of nRF Connect for Desktop from https://www.nordicsemi.com/Products/Development-tools/nRF-Connect-for-desktop/Download?lang=en#infotabs (for macOS this is 3.7.2, for Windows and Linux 3.7.1, because 3.7.2 was not needed and not released for these).
After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
In the Settings, click on “Add source”, enter the URL http://developer.nordicsemi.com/.pc-tools/nrfconnect-apps/3.7-apps/apps.json and click “Add”.
Back in the list of all apps, all apps should show up twice now, one with “official” below them and one with “3.7 compatible apps” below them. If you want to hide the incompatible versions, click on “Filter” and deselect “Official”.
Install the apps you need in the old versions and use them.

Test this and see if this solves the issue you are having.

If not can you share a bit more about the setup maybe?

How is the nRF connect for Desktop used with the testing software? what are you testing? Is there any error messages anywhere that you can share with us maybe?

If there is something failing in the wireless communication then a sniffer trace could maybe help us get to the bottom of this.

Jonathan

Thanks for the visual reference. Here are the two system reports.

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.
