Good to hear that you found a solution, thanks for the update.

Extended advertisements must also be supported by the Bluetooth adapter. Maybe that is why it did not work.

Thank you very much Vidar, unfortunately I wasn't able to take the time to learn Python (my programming experience is currently limited to Labview and VB 6.0 ;-).

At the end I took a different approach. First I was able to open "pc-ble-driver" in VS2022 and build the "heart_rate_collector". Then I modified the code to allow extended advertisements and to ouput the rssi. Once I got the EXE where I wanted, I simply run it using System Exec.vi in Labview.

Not the most elegant solution, but it's the quick and dirty way for someone looking for a very basic interface between the nRF52840 dongle and Labview.

Quick side note, I also tried to write a .NET C# application using Windows UWP BluetoothLEAdvertisementWatcher and some cheapo USB Bluetooth adapters from Amazon, but even after enabling the AllowExtendedAdvertisements property, I wasn't able to scan extended advertisements, only the BLE legacy ones.

Hello,

Attached below is a python script for the pc-ble-driver-py I quickly put together which will connect to any BLE device named 'TARGET_DEV_NAME' and start logging the RSSI. You can use it with the same dongle and FW you use with the Bluetooth low energy app.

test-devzone.nordicsemi.com/.../1362.rssi_5F00_logger.py

Steps for testing the script:

1. Install pc-ble-driver-py through PyPi: $ pip install --user pc-ble-driver-py

2. Change TARGET_DEV_NAME in the script to match your device.

3. Run script with python: $ python3 rssi_logger.py NRF52 <COM port for nrf52840 dongle>

After the connection has been established you should start seeing the measured RSSIs from the connection:

$ python3 rssi_logger.py NRF52 /dev/ttyACM0
Serial port used: /dev/ttyACM0

I do not have much experience with LabView, but I hope you will be able to parse the log output from it.
