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. 

    Regards,

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

    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:

    1. 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).
    2. After starting nRF Connect for Desktop 3.7 a prompt will come up about the 3.8 upgrade. Click “No” on this.
    3. 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”.
    4. 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”.
    5. 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. 

    Regards,
    Jonathan

    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!
