me176c-factory

A simple library, and optionally service to load the factory information (serial number, BT/WiFi mac address) from the factory partition on the ASUS MeMO Pad 7 (ME176C(X)).

Library

me176c-factory.c/h provides methods to load the factory information. See me176c-factory.h for details.

Service

There is a simple service implementation suitable for most Linux distributions. It mounts the factory partition temporarily on boot, reads the data and stores it in the runtime directory /run/me176c (compile-time configurable).

Building

Using Meson:

meson . build
ninja -C build

Usage

Run /usr/lib/me176c/me176c-factory <block-device>. In most cases, <block-device> should be /dev/disk/by-partlabel/factory.

The service then writes the information to:

  • /run/me176c/serialno: Serial number
  • /run/me176c/wifiaddr: WiFi hardware (MAC) address
  • /run/me176c/bdaddr: Bluetooth device (MAC) address
  • /run/me176c/environment: Above information as KEY=VALUE pairs

systemd

systemd and udev integration is enabled by default. It provides me176c-factory.service that starts the service on boot. Optionally, udev rules together with me176c-factory-bdaddr@<dev> and me176c-factory-wifiaddr@<dev> are provided to automatically set the WiFi/Bluetooth MAC address on boot.

OpenRC

OpenRC + udev integration can be enabled with -Dsystemd=false -Dopenrc=true. It provides the me176c-factory service. Optionally, udev rules are provided to automatically set the WiFi/Bluetooth MAC address on boot.

Packaging

  • Arch Linux: me176c-factory AUR package
