data_handler ready for chat messages
...
data handler is now ready for chat messages. I updated the data frame with an additional information -datatype- so we can determine if we received a file or a message. Each datatype will be saved into an own buffer. The gui has been updated as well, so we can forward data directly to a future chat module...

freq offset handling #81
...
first attempt just with pings. Station A sends a ping to Station B. Station B is detecting RX offset, adds it to the ping acknowledge frame and sends it back to Station A. Station A will then adjust the frequency
