Developed and delivered support for the MovingComm C120EV 4G LTE router within the DragonBluep/openwrt repository, focusing on expanding OpenWrt compatibility for MT7628AN-based devices. The work involved implementing a tailored device-tree configuration and establishing the initial network setup in C and Makefile, enabling out-of-the-box WAN connectivity and 4G functionality. Leveraging expertise in Linux kernel and device driver development for embedded systems, the contribution streamlined deployment and reduced integration effort for new hardware. This feature allows customers to quickly bring up the router with minimal configuration, addressing the need for rapid, reliable network provisioning in embedded environments without requiring manual intervention.
