Upgrade firmware

A wireless network comprises a set of nodes that can communicate with each other

by means of radio transmissions according to a set of routing rules (for passing messages between
nodes). ZigBee network includes three types of node:

1)

Coordinator:

This is the first node to be started and is responsible for forming the network by

allowing other node to join the network through it.

2)

Router:

This is the node with routing capability, and is also able to send/receive data.

3)

End device:

Only capability to send/receive data.

Different device role should burn different image. Burn the latest firmware using

JN51xx Flash

Programmer

. Four steps are required as below:
