5.5 Write command from remote node
A command from a remote node or from a smartphone to an addressed node invokes a
WriteLocalData
callback.
This callback can be used to process the commands or data received inside the network. In the application demo,
the
Appli_WriteLocalDataCb
function is the callback where data or commands will be processed. The
command/data flow can be visualised in the picture below.
