these Linux programs read out the measurements from the WEB/WITRN/GZUt/QWay U2/U2p USB power meter.

USB
|
|
===
|
|
|
|
`u2_usb` reads the measurements using the USB HID interface.
|
|
|
|
to compile the source code you require: gcc, make, hidapi library (libhidapi-dev).
|
|
then just run `make` and it will output the `u2_usb` binary.
|
|
|
|
run `u2_usb` to get the output in CSV format.
|
|
run `u2_usb -d` to get the raw and decoded output (useful for reversing and debugging).

Bluetooth
|
|
=========
|
|
|
|
to compile the source code you require: gcc, make, dbus library (libdbus-1-dev).
|
|
then just run `make` and it will output the `u2_bt` binary.
|
|
|
|
ensure the BlueZ Bluetooth stack is running:
|
|
sudo systemctl start bluetooth
|
|
don't forget to grant the permissions to access bluetooth devices:
|
|
sudo adduser $USER bluetooth
|
|
|
|
run `u2_bt` to get the output in CSV format.
|
|
run `u2_bt -d` to get the raw and decoded output (useful for reversing and debugging).
|
|
|
|
I did not implement the possibility to specify the Bluetooth adapter and device.
|
|
the program uses the first Bluetooth adapter it finds, and first device with the name starting with Qway_U2.
