Mesh upgrade
This package can help you upgrade the firmware of all the routers in a network from a single node.
Description and steps
1- A node must become main node, the main node will fetch the firmware for all the others. And expose it in the local network.
2- The main node announces the new firmware over shared-state-async
3- Other nodes with this package will get the news and try to download the firmware.
4- Once all the nodes have the firmware in their tmp folder the main node user will be able to schedule the safe upgrade of all the nodes (this last step is done synchronously).
5- After the specified time (60s default) all the nodes will start the safe upgrade process and the nodes will reboot.
6- The nodes will report that the new firmware has to be confirmed.
7- The main node user will verify that everything is in place an press the confirm button.
8- If the firmware is not confirmed after 600 seconds the routers will go back to the previous firmware.
