Simple Management Protocol (SMP) Server Fixtures

This repository provides SMP server fixtures for testing SMP client tools like smpmgr and smpclient without physical hardware, enabling integration tests in CI environments.

Available Fixtures

Serial Transport - Native Simulator

The smp_server.fixture.serial.native_sim fixture provides a Zephyr SMP server that runs natively on Linux and creates a pseudo-terminal (PTY) device for serial communication.

Building the Fixture

west build -b native_sim apps/smp-server -T smp_server.fixture.serial.native_sim

Running and Testing the Fixture

1. Run the fixture executable:

   ./build/smp-server/zephyr/zephyr.exe

2. The output will show the PTY device path:

   uart connected to pseudotty: /dev/pts/4
   *** Booting Zephyr OS build v4.2.0-6166-g8a72d776c5af ***
   [00:00:00.000,000] <inf> smp_sample: build time: Oct 19 2025 14:03:46
   

3. In another terminal, connect using smpmgr or smpclient:

   # Example using smpmgr (replace /dev/pts/4 with your actual PTY path)
   smpmgr --port /dev/pts/4 os echo hello

4. Stop the fixture with Ctrl+C

Notes

• The PTY device path (/dev/pts/X) will change each time you run the fixture
• This fixture is build-only in CI and is intended for local testing or integration tests in client tool repositories
• MCUboot is disabled (CONFIG_IMG_MANAGER=n, SB_CONFIG_BOOTLOADER_NONE=y) for simplicity
