µPCN

The Micro Planetary Communication Network (µPCN) is a free software project intended to offer an implementation of Delay-tolerant Networking protocols for POSIX operating systems (well, and for Linux) plus for the ARM Cortex STM32F4 microcontroller series. More precisely it currently provides an implementation

• of the Bundle Protocol (BP, RFC 5050),
• of the Bundle Protocol version 7 specification draft (version 22),
• of the MTCP convergency layer draft as specified in the specification draft (version 0),
• of the TCPCL convergence layer as specified in the experimental RFC 7242,
• of the CCSDS Space Packet Protocol (SPP),
• of a routing approach optimized for message-ferry micro LEO satellites.

µPCN is written in C and is built upon the POSIX API as well as the real-time operating system FreeRTOS. The source code of µPCN is released under the "BSD 3-Clause License".
For testing the system, check the README.txt file included in the tarballs linked below. In order to test the implementation on bare STM32 metal, a development board such as the STM32F4Discovery board is necessary. After installing the specific toolchain consisting of a cross compiler, FreeRTOS and a programmer, the program can be burned to the board and tested via the provided test programs.
