This is a low-level, cross-platform command prompt interface to PASCO Bluetooth devices. There are commands to scan, connect, disconnect and record data from devices etc.

The code aims to be cross-platform. Installation by

pipx install git+https://github.com/xhep-lab/cmdpasco.git

Start the command prompt by

cmdpasco

For help, enter ? or help at the prompt. There are commands for

• scan: scan for available PASCO Bluetooth devices
• connect: connect to a PASCO Bluetooth device using the six-digit device code
• info: show information about connected devices
• record: record data from connected devices to disk
• watch: plot data from connected devices in real time

E.g., here we connect to a device by ID number, record data at 1 second intervals, disconnect, and quit:

andrew@workstation:~$ cmdpasco
Welcome to the PASCO shell. Type help or ? to list commands.

(disconnected) connect 178-396
Device Smart Cart 178-396 connected
(Smart Cart 178-396) record 1
Saved data to cmdpasco_data_2025_09_01_15_26_54.txt
(Smart Cart 178-396) disconnect
Device Smart Cart 178-396 disconnected
(disconnected) quit

Contributions are strongly enouraged, especially from students using PASCO devices. Possibilities include:

• installation by Conda
• watch command that supports multiple measurements to watch
• record command that allows recorded data to be filtered
• Mock devices for testing - it's hard to develop the code as you have to have a PASCO device handy. Can we have a mock device for testing?
• And of course bug fixes!
