Has anyone tried to update firmware over the air (FOTA) using the example code provided by STM (LoRaWAN_FUOTA) in STM32WL software package?

[VA]

For this , I am using STM32WLJC1 Nucleo as my end node device.

I was able to generate the binaries as suggested in AN5554. I want to know how I can fragment this binary as required by LoRaWAN® Fragmented Data Block Transport Specification v1.0.0

and use the fragmented file to push using custom application server to network server(having multicast support, say things network ) so that end node receives the updates over air.

Any example ,resources or help to establish me this chain for LoRaWAN FOTA will be greatly appreciated.

Thanks in advance.

Hello,

We have done validation tests on different network operators as Actility, Senet or AWS, check section 9 in the AN5554. You will find here (https://blog.st.com/thingpark/) more ressources about Actility.

Unfortunately, we don't provide example, we only have done proof of concept.

Actility and ST use the same pattern of fragmentation and redundancy so you should be able to get a fully working FUOTA solution.

Hope it helps

Regards
