After making these modifications to the config_me.h file, click the Save button and the
Compile button along the top bar. The source files are compiled and the binary programming
file, Avnet_ATT_Cellular_IOT.bin , is saved to your default Download folder. Depending on the
browser you are using or the browser’s settings, you may be prompted for a location to save the
file.
Other noteworthy fields in config_me.h are:
–
FLOW_INPUT_NAME
– The HTTP IN port in the Flow project where you want to send sensor data.
In the default Flow image, this input is inside the Climate GET port and is named /climat e.
–
SENSOR_UPDATE_INTERVAL_MS
– The update period for sending sensor data to Flow. The
default for this is 5 seconds.
Programming
Disconnect, and then reconnect the USB cable from your laptop to the FRDM-K64F board to
force a board power cycle. Once the MBED drive is enumerated, drag and drop the
Avnet_ATT_Cellular_IOT.bin you just created to the MBED drive. This will program the non-
volatile Flash memory on the FRDM-K64F board with your application firmware. Programming
should take about 10 seconds, during which time the FRDM-K64F board green LED should go
through several flashing sequences.
Once programming is complete, unplug the USB cables from your laptop and from the AC/DC
power adapter. Then reconnect the cables, connecting the 5V USB power cable to the power
adapter first, followed by the SDA USB cable to the laptop.
