Hi ESP-IDF,

really really long story...

I put really many efforts to port Open62541 on ESP-IDF.

Here is what I've achieved:

https://github.com/Gfast2/open62541_port

But the connection is "nearly establisch", but still no 100%, I stucked here for days...

If some one is interested in, please drop in! This don't need extra hardware. Setup your WIFI in "make menuconfig" you are good to go.

under /main are open62541.h/.c which I got compiled from version 0.2 of this library's source. I did pay a lot to even get these two files.

Related disscussion are:

If you do let it up and running. use a OPC UA client to checkout the running Server:
