Sending data
This section provides command examples that used for sending user data.
Example 1: Send a two-byte data 0x1234
senddata 1234
After perform this command, user will see a success state which indicates
the command is correct. Due to the minimum transmission period(default
is 60 seconds), user data will not be sent immediately. It can only be sent
at the 60, 120, 180… second of system time. As you can see in above
figure, the user data is sent at the 60 second of system time.
Example 2: Perform two senddata commands in a short time. User data
are 0x5678 and 0x1234.
senddata 5678
senddata 1234
There will always keep one set of user data during the transmission
period. So the old data 0x5678 will be overwritten by new data 0x1234.
In this case, only the data 0x1234 will be sent.
