Step 3
After performing temperature and pressure measurements and storing data in buffers, each
demo board uses a random number generator to generate a number k in the range of 0 to 2
and waits for that amount of time (seconds) to send out a remote transmission request to
request node k to send in temperature or pressure data and display them on the LCD. The
received data should be displayed as follows:
received Tk 5 xxx.y
or
received Pk 5 xxxx.y
The demo board that transmits the data should display the following message:
send Tk 5 xxx.y
or
send Pk 5 xxxx.y
