Radiocrafts TinyMesh Modules

TinyMesh is a fantastically powerful multi-hop mesh protocolwith bidirectional wireless communications.

What really makes the protocol unique is that TinyMesh modules can transfer both regular data packets between host applications AND monitoring and control data packets. See the brochure here.
 
Network packages allow for 120 bytes of transparent data which can carry application layers like for instance Wireless M-Bus (European norm), MODBUS, DLMS/COSEM and KNX RF.

Monitoring and control packets are linked to physical I/O functions of the TinyMesh Modules. A nodes' input signal status can be polled, or the module can be configured to automatically generate a message when a defined condition is met. Click to view signal input capabilities.

The status of output pins on the module can be similarly modified by a message from the network coordinator. Click to view the output control capabilities.

All of this without requiring a host micro-processor!

All nodes in the TinyMesh network are physically the same. The definition between the coordinator and any other node is made by changing a configuration setting. It is also possible to define a node as a very low power 'end-node' to save power. See the end-node characteristics.


There are further additional features which help with network commisioning, optimisations and ease-of-use. TinyMesh special features
