Overview of the eZ430-Chronos and CC430 is
presented and followed by a short demo
showcasing the features of the standard Chronos
package. The next lab aims at getting Chronos to
communicate in peer to peer mode. Attendees will
then work with SmartRF Studio to configure the
CC430 RF settings and reapply new RF
configurations to their Chronos. The workshop
wraps up with an optional lab demonstrating
power (RSSI) meter application with the Chronos.

Tips:
1. Press the screwdriver down firmly when unscrewing to prevent stripping
2. Pry against the edge of the eZ-connector to lift the PCB out
3. Do not take the battery out of the battery holder

Lab 3 [BONUS]
RSSI Chronos Meter
Use your Chronos to measure TX signal
• We broadcast carrier freq. of 888MHz
• Notice how the RSSI value changes
Operate | Power Meter
• Move closer/away from the CC430EM to see differences
in reading
• Reading changes with
– Distance
– Interference / obstacles
– Antenna radiation pattern / characteristic
• Instructor’s CC430 is broadcasting
– Continuous RF carrier @ 888MHz
• Chronos measures power
– RSSI readout from RF1A (Radio) module
– 888 MHz with 400 kHz filter
