2 Running the Preprogrammed Link Test
2.1 Introduction
The CC1110 on the SmartRFCC1110 target
board is preprogrammed with a link test which
operates at 868.3 MHz, and uses GFSK
modulation and a bit rate of 2.4 kbps.
The link test runs a point-to-point communication
between a Slave and a Master node based on
the SimpliciTI 1.1.0 protocol.
First the Master and Slave nodes must be
configured as described in the following
sections. The two nodes will then establish a
link. When this link is established, the Master
starts to periodically send packets to the Slave.
Between each transmission, the Master goes to
receive mode and waits 250 ms for an
acknowledgement packet from the Slave. The
Slave node is in receive mode waiting for
packets from the Master. For each received
packet, the Slave automatically responds with
an acknowledgement packet.
2.2 Powering the boards
Place 2 AAA batteries in the battery holders
placed on the bottom side of each of the
SmartRFCC1110-868 boards. Place the jumper
on the power selection connector P1 between
pin 1 and pin 2 on each board.
Applying power to the SmartRFCC1110-868
starts the preprogrammed link test on the
CC1110 and the two LEDs on the board are on
for 1 s.
Warning! To minimize risk of personal
injury or property damage, never use
rechargeable batteries to power the board.
Do not leave the board powered when
unattended.
2.3 Configure the Master Node
Press the S1/MASTER button that is placed on
the left hand side of the board. When this
button is pushed, the two LEDs on this board
will blink rapidly. The Master now waits for a
Slave node to establish a link.
Note that the boards only respond to the first
button push. To reconfigure the board, the
board must be reset, see point 2.9 in this
manual.
2.4 Configure the Slave Node
On the other board, press the S2/SLAVE button
that is placed on the right side of the board.
When the button has been pushed, the two
LEDs on this board will blink very slowly until a
link with a Master node is established. Note that
establishing the link may finish in less than 1 s
depending on the environment.
It is important to keep distance (more than 1
meter) between the two nodes when they are
trying to establish the link to avoid saturation.
This is because full output power (12 dBm) is
used for this communication between the nodes.

2.7 Antenna Performance
The PCB antenna length on the
SmartRFCC1110-868 is tuned for optimal
performance with two AAA batteries present in
the battery holder. As this antenna is directive,
see DN024 www.ti.com/lit/swra227, it is
important to place the two nodes so that the
arrow in the silk print next to the antenna on
both boards points upwards towards the sky for
optimal performance.
2.8 Range testing
The preprogrammed link test is well suited for
range testing. Place the Slave in an open field
and bring the Master a known distance away.
Use the LED signaling to decide the link quality.
Note that the environment, antenna, etc greatly
affect the range, see DN018
www.ti.com/lit/swra169.
2.9 Resetting the board
The recommended reset sequence is:
Remove jumper on P1 completely
Push one of the buttons to discharge the
large capacitor on the power line. If this
capacitor is not discharged, the
SmartRFCC1110-868 boards may continue
to run the current application until the
capacitor is discharged. This may take
several seconds.
Replace the jumper on P1 to power the
board again
