- test/kiss_client.py: Full-featured KISS modem client library Supports all 14 config commands, KISS frame encoding/decoding, signal quality reporting, packet send/receive Can communicate over serial ports or file-like objects (stdin/stdout) - test/test_integration.py: Integration test suite using kiss_client.py Tests radio configuration, parameter setting, KISS frame encoding/decoding Designed to run against modem or simulator Run with: python3 test/test_integration.py - test/main_simulator.cpp: Hardware simulator scaffold for native platform Mocks SX126X radio with configurable state Communicates via stdin/stdout for easy testing Note: Full compilation requires Arduino.h mock (future work) Verified: seeed_xiao_s3_wio_sx1262 and heltec_v3 still build without errors
