LS RESEARCH ModFLEX SiFLEX02-HP Quick Start Manual

The quick start demonstration presented here is
referred to as the Ping Pong Range Test. The Ping
Pong Range Test allows a user to easily verify range
between two modules via feedback from three
flashing LEDs.
Running the Ping Pong Range Test requires the use
of two development boards. One board will be the
master, and the other board will be the slave. The
master periodically transmits packets to the slave. If
the slave receives a packet, it will flash its LEDs and
transmit a packet back to the master. If the master
receives a packet from the slave, it will flash its LEDs.

Powering the Dev Boards

There are two power supplies required on the
SiFLEX02-HP module, a 3.3v supply, and a 4v supply
for the RF power amplifier. The 3.3v supply can be provided through one of the following three options. Make
sure that jumper J2 is properly configured based on which 3.3v supply source you are using.

AA batteries

USB

External DC power supply
The 4v supply needs to be provided by an external DC power supply capable of sourcing a minimum of
600mA. The 4v supply needs to be connected to pins 6 and 7 on the module, which are accessible on header
strip J14 on pins 6 and 7. The external 4v power supply ground should be connected to a ground pin, which
can be accessed on header J16 GND or J15 GND.

Enabling Ping Pong Range Test

One board needs to be configured as a master, the other as a slave.
As Master
1. Press the RESET button and the USER1 button simultaneously.
2. Release the RESET button.
3. Wait until green LED1 is lit, then release the USER1 button.
As Slave
1. Press the RESET button and the USER2 button simultaneously.
2. Release the RESET button.
3. Wait until red LED3 is lit, then release the USER2 button.
