pynrfjprog

pynrfjprog is a Python wrapper around the Nordic Semiconductor nrfjprog DLL (dynamic link library). The code is open source and available on GitHub.

Installation

To install pynrfjprog, into your Python environment, run the following command:

pip install pynrfjprog

As always, it is recommended to use a virtual environment to manage your Python packages.

Usage

Use enum_emu_snr() to enumerate the serial numbers of the connected programmers:

from pynrfjprog import LowLevel

with LowLevel.API('NRF52') as api:
    serial_numbers = api.enum_emu_snr()
    if serial_numbers is None:
        print("No programmers found")
    else:
        print(f"Found {len(serial_numbers)} programmers with serial numbers: {serial_numbers}")

enum_emu_snr() returns a list of serial numbers (e.g. [960095105, 1051285627]). If no programmers are found, it returns None.
