A simple RTT client using Python 3 and pynrfjprog

PyRTT Viewer

This is a simple Python 3 script for simple RTT interaction with an nRF5x device.

If you just want to use it directly, you can install using pip:

pip install pyrtt-viewer

Then you can run the script as a normal executable:

pyrtt-viewer -h

Usage

pyrtt-viewer [-s <serial-number>] [-c <rtt-channel>]

If you think you'd like to modify the script a bit, install it as a local package:

pip install -e .

Requirements

• Python 3.x
• pynrfjprog -- pip install pynrfjprog

pyrtt-viewer's Issues

NRFJPROG DLL: -254 INTERNAL_ERROR

It runs fine on some machines, but on others it fails with this output from Python:

Traceback (most recent call last):
File "pyrtt-viewer-mt-original.py", line 188, in <module>
main()
File "pyrtt-viewer-mt-original.py", line 174, in main

raise APIError(result, error_data=self.get_errors())
pynrfjprog.APIError.APIError: An error was reported by NRFJPROG DLL: -254 INTERNAL_ERROR.

It runs fine on Ubuntu 20.04, Windows 7, Windows 10.

It fails on few other Ubuntu 20.04, Kubuntu 21.10, and two macOS.

All systems have installed Segger JLink software pack, Nordic Command Line Tools, and pynrfjprog.

RTT-Session not closed after terminate the script (CTRL-Z in terminal)

Session not closed correctly. After termiante / stop the script in the terminal it is not possible to open RTT-viewer again.

Make setup script for use with pip

Unable to accept input

I have an NRF device with CLI over RTT. If I connect using JLinkRTTClient or RTTViewer (on Windows), I can interact with the prompt. However using pyrtt-viewer, the device does not appear to receive input. I can see output coming out, so RTT is connected, but any input is not received by the device.

I attempted this on both Mac OSX (High Sierra) and Windows 10. Both behaved the same.

Make device selection easier on Linux/MacOS

On Windows, the nrf.connect_to_emu_without_snr() works well as it pops up the JLink dialog to select the device. However, on MacOS and Linux, there is no such dialog.
Instead, you should be able to get the available devices and select your favorite in some easy way.
