1. Adding the quectel-community layer to your build

In order to use this layer, you need to make the build system aware of it.

Assuming the quectel-community layer exists at the top-level of your yocto build tree, you can add it to the build system by adding the location of the quectel-community layer to bblayers.conf, along with any other layers needed. e.g.:

BBLAYERS ?= " \
  /path/to/yocto/meta \
  /path/to/yocto/meta-poky \
  /path/to/yocto/meta-yocto-bsp \
  /path/to/yocto/meta-quectel-community \
  "

2. About This Layer

This layer adds kernel modifications to support the following Quectel hardware:

• EC25 LTE Module

Once the Linux Kernel adds support for a module it can be removed from this layer.

This layer also adds a set of three Point-to-Point Protocol daemon scripts which allow the use of a pppd call questel-ppp command. Both these scripts and the kernel modifications are based on instructions provided by the Quectel WCDMA&LTE Linux USB Driver User Guide.

This layer is not produced or supported by Quectel. It is developed by users of Quectel hardware who wish to add support to Yocto systems. Initally the development focuses on supporting the hardware under a Raspberry Pi 3.

3. Using the PPPd scripts

Once your Quectel hardware is connected and the appropreate USB driver is associated with it you can initiate a call with:

pppd -E call quectel-ppp

Before using the script you will need to set the appropriate Access Point Name (APN), Username and Password for your LTE network connection. To do this set LTE_APN, LTE_USERNAME and LTE_PASSWORD environment variables before calling the pppd script with the -E option.
