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

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?

Can you link me to the instructions you are talking about?

Just to clarify, you press restart after flashing, and you're then unable to find the DK from your phone, correct?

Thanks very much Einar, it's Section 3 - 'Running a first test' of this document:

Yes, I press reset after flashing and the nRF Toolbox app is unable to connect.on either my iPhone or iPad Pro.

As confirmation that Bluetooth is functional on my iPad Pro, I was able to connect to my Bose SoundLink Mini speaker and stream music to it.

OK I see.

Could you show me what your DK is printing over serial? Maybe it's giving you error messages.

You can access this for example in the nRF Connect SDK for VS Code while your device is connected through USB.

Thanks again Einar, I have launched the terminal monitor in nRF Connect SDK for VS Code, but am not seeing USB traffic, what connection and display options should I be using please?

In the nRF Connect tab of VS Code you should find a "Connected devices" section.

There you can choose the COM port of your device, and VS Code will display the serial traffic under "nRF Terminal"

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?
