JP Norair has been hacking away with the TI 433 MHz Chronos.
My project is OpenTag, which is a 433 MHz centric IoT/M2M stack. It’s 433-centric because it implements DASH7 and because it makes design assumptions that multihop is not of great importance (at 433 MHz, it certainly isn’t). You can check the wiki, which is admittedly incomplete, but it’s a good starting point.
JP reports that some of his friends at Wizzilab are doing great things with the Chronos 433 kit. They’ve even put together a free IDE with Code::Blocks and mspgcc.

wow! this is very nice!
I read some articles about Dash7 and I want to implement some projects using Dash7.
