Ok so you want to create a YSFReflector server which provides one room. You can download the server's source code at
https://github.com/g4klx/YSFClients/tree/master/YSFReflector
You have to compile it yourself and then run it on your computer or on a server. Please note that we do not provide official support for this as YSFReflector is not a SharkRF product.
You can also run a SharkRF IP Connector Protocol server which handles multiple modes. This is also available as source code at
