The two examples simplewifi and simplewifi-rpc are currently the only examples that have been tested on hardware.

The simplewifi example is a simple method showing how to use async servers with Nim. However, as of Nim 1.4, there are still some challenges running async with ORC on small devices. This should get better over time and may work depending on your paramters.

For production usage, it's recommended to use one of the simplewifi-rpc methods. Using socket select allows efficiently servicing RPC calls without requiring async. However, this means only one RPC call can be handled at a time. This could be worked around by spawning more tasks or sockets, but is sufficient for many cases.
