Is Simba for esp8266 supposed to be working now in IDE 1.2.0 and PlatformIO CLI 2.9.0?
According to the docs it is!
Hello,
I’m sorry for the inconviniance. The ESP is not yet supported when Simba is built by PlatformIO. I’ll add support for the ESP next week, hopefully.
On a side note, Simba has not been used extensively with the ESP yet and there are functionality missing in the ip-stack, TCP for example. Since there are users interested in using Simba on the ESP, I’ll prioritize to implement this.
I’ll let you know when it is ready.
I hope you’ll give Simba another try 
Erik
Hi again,
the simba framework has been updated and builds successfully. Though, as I wrote in the previous response, there are many essential features missing in Simba for the ESP. I’m adding features on a daily basis, currently focusing on TCP and UDP. Please have a look in the Simba repository on Github (GitHub - eerimoq/simba: Simba Embedded Programming Platform.) if you are intrested in the progress.
