Mesh network

Powerful way to route observations. Range is extended by allowing data to hop node to node and reliability is increased by “self healing”, the ability to create alternate paths when one node fails or a connection is lost. It has the following advantages:

• Network setup is simpler
• More flexibility to expand the network
• Increased reliability in environments where routers may come and go due to interference or damage

Digi XBee radio configuration

Below you will find the required configuration for the XBee radios used in the M2MBridge Mesh Network. Using Digi XCTU tool you need to do the following:

• Set the baud rate to 230400 [8]
• Set the API enable setting to API mode without Escapes [1]

serial configuration

• Make sure that all bridges participating in the same mesh network share the same network identifier. Multiple mesh network can operate in the same zone as long they have different Network IDs.

Assumptions

1. the XBee 900HP radio has been configure with digimesh firmware https://www.digi.com/support/productdetail?pid=5576&type=firmware
2. the XBee 900HP radio must be connected to /dev/ttyUSB0 with this configuration: 230400/8/N/1/N - API 1
