Install/Setup of Terminal Program
You need a terminal program to monitor the output from the FRDM-K64F program. The mbed
site (
https://developer.mbed.org/handbook/Terminals
) provides instructions for setting up a
terminal on a Windows, MAC, or Linux computer. With a terminal program installed, configure
the following parameters:
–
Baud = 115200
–
Stop Bits = 1
–
Parity = None
–
Data bits = 8
–
Flow Control = none
–
COM port set appropriately (in the above screen shot, it is COM19)
Running the IoT Flow and M2X Program
The final step is running the IoT Flow/M2X programs and checking to see if everything works.
FRDM-K64F Operation
: The user LED on the FRDM-K64F board should be RED when the
wireless connection is first powered on. It turns BLUE when it successfully connects to the
AT&T network and then either green, magenta or turquoise, depending on the response from
the Flow project implementation. The data being sent can also be monitored through the
terminal connection that was previously set up.
Flow/M2X Operation
: To verify messages from the board are arriving in Flow, go to the Flow
project and click the
Debug
tab
at the bottom of the canvas. Because the board is doing an
HTTP GET, data currently enters the Flow design through the bottom HTTP IN port. Messages
with sensor information start appearing. There are debug messages from both the input and
output debug ports. You can enable/disable these debug messages by clicking the solid part to
the right of the port.
