Just found this LoRa (+Sigfox + WiFi + Bluetooth + cellular/LTE) based mesh project by pycom going by the name of PyMesh. They’ve built and delivered a GTM-like device called the PyGo, and have a new PyGo2 which adds cellular/LTE link. The first version was a successful Kickstarter project, and they successfully Kickstarted two development boards too. All of the above are available via their store, though some are back-ordered.
Open Source
Pycom is the creator of a number of development boards and their firmware is open source enabling our developers to download our source code and make contributions in the spirit of open source.
