CycloneTCP / CycloneSTP / CycloneBOOT

CycloneTCP is a dual IPv4/IPv6 stack dedicated to embedded applications. CycloneTCP conforms to RFC standards and offers seamless interoperability with existing TCP/IP systems. By supporting IPv6 and many application protocols (FTP, TFTP, HTTP, SMTP, MQTT, MQTT-SN, CoAP, SNMP, SNTP, NTS, Modbus/TCP, Syslog and WebSocket). CycloneTCP eases deployment of next-generation Internet. The stack is distributed as a full ANSI C and highly maintainable source code.

CycloneSTP is an implementation of STP (Spanning Tree Protocol) and RSTP (Rapid Spanning Tree Protocol) algorithms suitable for resource-constrained microcontrollers. STP and RSTP are network protocols that can be implemented on Ethernet bridges to ensure loop-free LAN topologies. Spanning Tree Protocol allows a network design with multiple physical paths and backup links for redundancy purpose. If a link fails, STP or RSTP automatically reconfigures the network to establish a new loop-free tree topology.

CycloneBOOT is a secure firmware update solution targeting 32-bit microcontrollers. It provides a reliable and secure method for booting and updating the firmware of your device. Tailored to work with a variety of ARM Cortex-M based microcontrollers, CycloneBOOT ensures a seamless boot process every time.

CycloneTCP / CycloneSTP / CycloneBOOT are available either as open source (GPLv2 license) or under a royalty-free commercial license (non-GPL license). We also propose an *evaluation license* (90-day license in source form) with technical support for an easier onboarding and effective evaluation of our software.
