AT Command Parser External Module for Zephyr (based on cAT library)

[mustafaabdullahk]

Hello Zephyr community,

I'd like to announce libcat-module, a Zephyr external module that integrates the cAT library for AT command parsing and handling.

What it does:

• Provides easy-to-use AT command parser functionality
• Supports command registration, read/write/test/run operations
• Thread-safe with mutex support
• Handles unsolicited responses

Integration:

Simply add to your west.yml:

manifest:
  remotes:
    - name: amazeng
      url-base: https://github.com/amazeng-co

  projects:
    - name: zephyr
      remote: zephyrproject-rtos
      revision: main
      import:
        name-allowlist:
          - cmsis_6
          - hal_nordic
          - hal_stm32
          # Add other required HALs here
    
    - name: libcat
      remote: amazeng
      repo-path: libcat-module.git
      revision: main
      path: modules/lib/libcat
      submodules: true

Then enable in prj.conf:

# Enable the LIBCAT module
CONFIG_LIBCAT=y

# Enable serial support (required for AT command communication)
CONFIG_SERIAL=y

Tested on: nucleo_f446re (should work on any board with UART support)
