nRF Connect for Desktop Programmer V2.2.0 and Heart Rate Monitor Demo

alwalker

I have connected a nRF5340 DK board which the Programmer can connect to. I then drag the two .hex files for the Heart Rate Monitor demo over to the File Memory Layout window, however the following commands are still grayed out:

  • Erase all
  • Erase & write
  • Save as file
  • Reset
  • Write
  • Read

What am I missing please?

    Hello!

    There is a known issue with the newest version of the programmer app and the nRF53. This will be fixed in a future update of the app.

    Meanwhile you should be able to program your DK if you roll back to nRF Connect 3.7 and Programmer v1.4.11 following these 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).
    2. After starting nRF Connect for Desktop 3.7 a prompt will come up about an available 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.

    Best regards,

    Einar

    Thanks very much Einar, I was able to follow your instructions fully and the board does now appear to be programmed based on doing a memory read.

    Per the instructions, I've pressed the reset button on the board and the green LED5 pulses periodically. No other LEDs illuminate.

    However when I start the latest version of nRF Toolbox just downloaded from the iOS App Store on either my 1st gen iPad Pro or iPhone 12 mini, when I try to connect via Bluetooth, no entries appear.

    All that is displayed is 

    SCANNING...

    Am I missing something please?

    There's definitely something not right!

    The terminal window continuously scrolls with the same block:

    Oh, that doesn't look good

    Could you try to compile and flash the Heart Rate Monitor Demo in VS Code, and see if you still get these errors?

    Hi Einar,

    Thank you for your reply, I can't find the source code files for the Heart Rate Monitor online, just a link for the folder with the two .hex files

                                          Peripheral_Heart_Rate_nRF5340_DK.zip                                     

    Do you have a URL for the application project please?

    I also saw something about an issue with macOS where the data packets over USB were getting truncated, but I can't immediately find it. Could this be the problem please?

    Workaround 2

    If MSD and VCOM are not needed at the same time, it is possible to disable the MSD component on the J-Link, freeing 2 EPs so that these ones can be used for VCOM to support 512 byte packets. In order to disable the MSD component, please do the following:

    • Connect the J-Link-OB to your PC
    • Start J-Link Commander
    • execute the following command (without quotes): "MSDDisable"
    • Quit J-Link Commander
    • Power-cycle J-Link-OB

    To re-enable the MSD component, please perform the same procedure as above but use the "MSDEnable" command instead.

    This is what I get when I open JLinkConfig, it's not obvious how to follow the workaround instructions:
