Integrating AT Slave example of LoRaWAN and Sigfox on STM32WL

[Nikhil D&K]

Hello developers,

I am currently developing all in one AT Slave firmware for STM32WL, which can handle both lorawan and sigfox AT commands. I have tested both AT Slave example of Sigfox and LoRaWAN one by one and  it's working as expected.

 When i open the .ioc file of this examples (AT Slave LoRaWAN and Sigfox) in CubeMX,  i can see it doesn't allow to enable the Sigfox/LoRaWAN middleware in LoRaWAN/Sigfox example. 

 

So i would like to know how i can enable both the middleware in same firmware, so that my master device can leverage the use of both technologies (LoRaWAN & Sigfox ) in the same chipset.

You're just going to have to study the code, and work out how to merge the two.

Are you looking to do both LoRaWAN and Sigfox "simultaneously", or just have a single image that can be switched to either LoRa or Sigfox mode ?

Hello @Andrew Neil ,

In my application i would be publishing hourly data on LoRaWAN server and Sigfox  backend one at a time. So looking to genrate a image of AT Slave in which i can switch between this modes.

 

Yes while studying its .ioc configurations, i bumped into the issue that cube mx is not allowing me to enable the Sigfox midleware in LoRawan application.

 

I also have refered this video https://www.youtube.com/watch?v=HsrL-7WmhUE of end device co-existence of both technologies but the resource downloaded doesnt have .ioc file nor it shows how to enable both midllewares in same project..

It's a complete project - so, presumably, doesn't need an .ioc file. You just build it as-is.

And the demonstration shows that it does have both Sigfox and LoRaWAN in the same project - it only takes a button switch to go between them.

Perhaps @STTwo-32 can comment further?

Alternatively, there's the 3rd-party stack mentioned in that post.
