The Weightless End Device Module (EDM) is a

Low-Power Long Range module with a full Weightless protocol stack up to the AT command interface.

The AT command interface offers rapid time to market. The module is an easy to use approach to bidirectional wireless communication. The End Device Module complies with the open, license-free Weightless protocol specifications. Build your own field devices or contact us for customized devices built around the EDM.
