ble_auto_testing

This project is used to automatically run BLE applications remotely, at the same time sniff the BLE packets, then save to a file, and finally parse the file to verify TIFS and other parameters in the future.

The related project is pcapng_parser.

Usage

Hardware setup

In this test, two MAX32655 DevKit boards are used.

Following the instructions in the README of project VSCode-Maxim, program the BLE5_ctr project into the two DevKit boards.

Then set up the test as the following figure shows.

Find the devices on a Ubuntu machine

NOTE
The sequence of powering up the board and plug in the USB cables will effect the ttyUSB*.
Suggest sequence:
Power up DevKit 0 -> /dev/ttyUSB0
Plug in DevKit 0 UART3 cable -> /dev/ttyUSB1
Power up DevKit 1 -> /dev/ttyUSB2
Plug in DevKit 1 UART3 cable -> /dev/ttyUSB3

It is helpful to use "ll /dev/serial/by-id" to check the serial ports.

Local test

Windows

In a Windows terminal, cd the source code folder.

.\venv\Scripts\activate
python -m ble-auto-testing -h

In the virtual environment, run the test.

python -m ble-auto-testing --interface COM4-None --device "" --brd0-addr 00:11:22:33:44:11 --brd1-addr 00:11:22:33:44:12 --sp0 COM9 --sp1 COM10 --time 30 --tshark "C:\Program Files\Wireshark\tshark.exe"
