Device Firmware Update Over 6loWPAN

[Mariswamy]

Dear Team,

We are developing an Vibration Sensing System, it contains nodes and gateway where all the nodes and gateway are present in the secured mesh network.

And node is an asset tracking device it push the data to the gateway using mesh network concept, Gateway receives the data from the end node in mesh network and it sends the data to the cloud using one of the Internet protocol. 

In our scenario we want to do FOTA for all the nodes using 6loWPAN - IPV6 (IEEE802.15.4 stack), so that we need 6loWPAN related libraries for nRF52840 Controller.

Please provide your suggestions on this.

Thanks & Regards,

Hi,

I'd recommend you take a look at our DFU over Thread solution (Thread Secure DFU protocol) if you havnen't already. It may be a good starting point, even if you don't intend to use the same protocol as in the example (thread/coap). The process of storing and activating FW images will still be the same ( you can use the same bootlaoder).
