Run an Application
This section assumes that “Build and Load a Sample Application” on page 13 has been successfully completed
and that the heart rate monitor application has successfully been downloaded to the WICED Smart tag.
Before the application can be tested, the power supply for the tag must be selected.
USB Powered Application
During programming, the tag is powered by the USB interface. After programming is complete, the newly
downloaded application automatically runs and no further action is needed. Further attempts to download an
application will fail because the UART port is no longer configured for downloads.
The Reset button must be momentarily pressed to enable downloads again.
Coin Cell Powered Application
To run the application from a CR2032 coin cell:
1.
Disconnect the tag from the PC USB interface.
2.
Set the position of the switches on the right side of the board (
SW2
and
SW3
) to the VCOIN positions, as shown
in Figure 4 . The switches should now be set to the opposite positions of those used for programming.
3.
Install a CR2032 coin cell in the battery holder on the bottom of the tag. Ensure that the battery polarity is correct.

Note:
If the problem persists after following the instructions above, the EEPROM on the WICED Smart
tag may be corrupted. See the instructions in “Recovering a Corrupt WICED Smart Tag” on page 27
to erase the EEPROM on the tag.
