SMPClient

✓ import smp

✗ from smp import SMPClient

Connect to a remote MCU over TCP, send an echo request, and list management groups.

import asyncio from smp import SMPClient, Group async def main(): client = SMPClient("tcp://localhost:6500") await client.connect() # Get echo response echo = await client.echo(data=b"hello") print("Echo:", echo) # List groups groups = await client.get_group_list() print("Groups:", groups) await client.disconnect() asyncio.run(main())

Debug

Known issues

breakingv4.0.0 dropped Python 3.8 support. Upgrade to Python >=3.9.

fix

Ensure Python 3.9+ is installed.

affects: <4.0

breakingv4.0.0 changed default line length from 8192 to 127 bytes for encode(). Override if using larger frames.

fix

Use `SMPClient.encode(data, fragment_size=8192)` if 8192 bytes is required.

affects: >=4.0.0 <4.0.0

gotchaTop-level imports changed in v4; 'from smp.client import SMPClient' no longer works.

fix

Use 'from smp import SMPClient' instead.

affects: >=4.0.0

deprecatedThe 'session' module is deprecated in favor of the new client interface.

fix

Migrate to SMPClient (import from smp).

affects: >=3.0 <4.0
