2.2 Recommended Application Connections
Figure 1 shows the minimum circuit connections required for the ProFLEX01 module,
when programming/debugging with the MSP-FET430UIF USB debugging interface. The
LEDs and USER buttons are needed for Ping Pong Range Test built into the LSR
firmware. The LED’s are also used during normal operation, and flash to indicate module
status (UART activity, RF activity, and heartbeat).
The reset (nRESET) pin (14) is active low. On the ProFLEX01 module it is pulled high
with a 47k resistor. To reset the module, pull the pin low to ground for at least 2S.
This is necessary to ensure a proper reset of the module.
In order to wake the module from sleep mode, an additional input signal (WAKEUP) with
interrupt capability on the ProFLEX01 module needs to be used. For simplicity it is
recommended that this be connected to the Host UART RX signal. This connection is
shown in Figure 1 To wake the ProFLEX01 module out of sleep simply send a dummy
byte to the module. See Section Error! Reference source not found. for further
information on wakeup from sleep options.
