I have found a LoRaWAN library that works in the esp-idf and I am trying to integrate it into the ulp-riscv example, however I am having trouble figuring out how to handle the c++ components of the library.
I have seen other posts trying to get C++ to work like this:
https://www.esp32.com/viewtopic.php?f=1 ... a51990bc02
There is a few examples of how to use C in C++, but not the other way around.
The error I'm getting is:
Code: Select all

But yet to have much success, I am likely just approaching it wrong...
Has anyone had success with a similar problem?
Cheers
