Send UDP Data to a Specific Remote Host #SSENDUDP
While the module is in command mode, this command sends data over UDP to a specific remote host.
UDP connection has to be previously completed with a first remote host through #SLUDP / #SA.
Then, if data is received from this or another host, data can be sent to it.
Like command #SSEND, the device responds with ‘> ‘ and waits for the data to send.
Test command reports the supported range of values for <connId>,<remoteIP> and <remotePort>
