v1.2.0

ZecTrix NOTE4C Devkit firmware version 1.2.0

Built with ESP-IDF 6.1 for the four-colour Note4C. Supports Local REST, Tesserae Cloud and Relay.

• Cloud setup with a fixed URL, an eight-digit claim code and an optional Device ID.
• Independent saved connection settings, credentials and server intervals. Switching modes or changing Wi-Fi/refresh speed keeps an existing pairing when its endpoint and ID stay unchanged.
• Setup header with saved identity, connection, endpoint, firmware version and setup IP.
• The same Unpaired instructions for confirmed Local REST, Cloud and Relay removal, with 24-hour sleeps. REST/Cloud attempt token recovery first and retry discovery on later wakes. The 20-second setup hold and low-battery protection remain available.
• Cross-signed HTTPS certificate support and successful TLS connection logs, with certificate and hostname verification enabled.
