fix: accept pure decimal node IDs in CLI by Cryptoteep · Pull Request #992 · meshtastic/python

Cryptoteep · 2026-10-06T21:36:06Z

This PR implements parsing for node IDs allowing prefix-less pure decimal inputs to be parsed as decimal node numbers, while prefixed inputs (! and 0x) are parsed as hexadecimal, satisfying issue #464. If parsing fails, it falls back to node DB lookup.

Fixes #464

Summary by CodeRabbit

Bug Fixes
- Improved destination handling when sending messages. Prefixed hexadecimal IDs, digit-only IDs, and other sufficiently long IDs are now interpreted according to their format.
- If a destination can’t be interpreted directly, it can be matched against the node list. Unrecognized destinations now produce a warning instead of a parsing error.

📝 Walkthrough

Walkthrough

MeshInterface._sendPacket parses destination strings as hexadecimal or decimal according to their format. When parsing fails, it can look up the destination in the node database. Tests cover these parsing and lookup cases.

Changes

Destination parsing

Layer / File(s)	Summary
Parse destinations and resolve node IDs `meshtastic/mesh_interface.py`, `meshtastic/tests/test_mesh_interface.py`	`_sendPacket` parses prefixed and qualifying implicit hexadecimal strings, and parses digit-only strings as hexadecimal at eight characters or decimal at other lengths. Failed parsing falls back to node database lookup. Tests cover parsing and lookup, and mock optional imports when unavailable.

Entering an eight-digit decimal node number, such as 12345678, sends the message to a different node than intended. Unresolvable destinations can also be sent to node 0 when the node list is empty. Fix the decimal parsing before merging.

Explanation

Issue #464 requests numeric node IDs and 0x- or !-prefixed hexadecimal IDs. The parser handles decimal strings except when they contain exactly eight digits. It parses "12345678" as hexadecimal (305419896), and the new test asserts that behavior. This conflicts with the PR description's claim that prefix-less decimal inputs parse as decimal.

to remove only a recognized leading “!” or “0x” prefix; preserve any embedded

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Parse eight-digit decimal destinations as decimal.

If a user supplies 12345678, this branch sends to 0x12345678 instead of node 12345678. The numeric path does not check the node database, so it can send to the wrong node. Parse every prefix-less digit-only destination as decimal. Require ! or 0x for hexadecimal digits, and update the assertion at Line 467 in meshtastic/tests/test_mesh_interface.py. The PR objective specifies decimal parsing for prefix-less decimal inputs.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Stop sending when the node database is unavailable.

If parsing fails while self.nodes is empty, this branch only logs a warning. nodeNum remains zero, and _sendPacket continues with meshPacket.to = 0. Reject the unresolved destination as the nonempty-database branch does.
