Central Transmitter
For this evaluation board, a Nordic module (nRF2723) is used
as a transmitter. In general, any Nordic RF module with an
nRF24xx IC and external antenna connection can be used as
a transmitter, however additional software development could
be required. To minimize programming and hardware devel-
opment time, the transmitter can be made of a Nordic RF
module with nRF24xxIC along with Nordic Motherboard
(nRF6310) which are included in the Nordic starter kit
nRF6700. The user can download the transmitter.hex file in-
cluded in this kit onto the Nordic module in order to use it as
a transmitter to send a shutdown or Panel-Mode signal to-
wards the receiver. The motherboard has buttons that can be
manually connected to the GPIO pins from the module. By
doing this, the transmitter module will receive button input
from the user and send an appropriate signal towards the re-
ceiver located on the SM3320-RF-EV board.
Both sample codes and hex files for the receiver and trans-
mitter are provided in the .zip file.

4) FLASH PROGRAMMING
A Nordic Motherboard (nRF6310) is required to program the
transmitter and receiver ICs. The sample code and hex files
provided can be used as a start to program both ICs. Please
remove R101 and R102 from the board before downloading
the .hex file into the receiver. The receiver IC in the SM3320-
RF-EV board is pre-programmed with functions to enter a
reset condition or to operate into a forced Panel-Mode con-
dition. Logic high will appear on P0.0 and P0.1 of the receiver
IC once an appropriate signal command is received from the
transmitter. The user also has the flexibility to program the
flash memory in the receiver IC by using the 10 pin connector
(J101 on schematic) located in the board. These 10 pins
should be connected with the external ISP interface on the
Nordic Motherboard (nRF6310) to enable the in-circuit pro-
gramming. Below is the table of pinouts for the 10 pin header
on SM3320–Rf-EV board and an external ISP interface from
the Nordic Motherboard .
