Momentum Firmware Code Review

Review firmware code changes with focus on Momentum-specific requirements:

Security Checks

• Verify no hardcoded credentials or sensitive data
• Check for buffer overflow vulnerabilities in C/C++ code
• Validate input sanitization for user-facing functions
• Ensure proper memory management (malloc/free pairs)

Firmware Compatibility

• Confirm changes maintain backwards compatibility with existing apps
• Verify SubGhz frequency ranges stay within legal limits (281-361, 378-481, 749-962 MHz)
• Check GPIO pin configurations don't conflict with external modules
• Validate NFC protocol implementations follow standards
