# My Motivation:
My MQ PRO is connected to a Waveshare LORA hat, I want to make it work but the default device tree conflicts with some of the pins my HAT uses. So I decided to 'fix' this by putting a better device tree on my board.

In the install steps above we reconfigure the system to use the correct MangoPI MQ pro device tree instead of the Sipeed Lichee RV one. In the install steps above we reconfigure the system to use the correct MangoPI MQ pro device tree instead of the Sipeed Lichee RV one.

You can make this permanent by, as root, copying `tools/mqpro-status-led.service` to `/etc/systemd/system/`, running `systemctl daemon-reload` then `systemctl enable --now mqpro-status-led.service`.
Other control options are available, `sudo cat /sys/devices/platform/leds/leds/blue\:status/brightness` shows a list and the current selection. Most do not work or are not very useful; ymmv.

## MQ Pro GPIO
Providing a full GPIO how-to is beyond the scope of this document, I use GPIOd to do this. But have also used direct pinctl control via the `/sys/class/gpio` tree.
