FW MODES
The board has the option to run Operational / Demo Firmware or Test/HCI Firmware. Within the Demo FW is the
option to have the board run as either a Beacon or as a Sensor platform. Selection of the desired FW version to
be loaded at power-up is done by two jumpers on J19.
Power to the board should be off prior to changing either one of these jumper settings. Upon power-up, the jumper
selection will be read and the appropriate FW version will be loaded into the SoC.
The lower row determines if the board comes up in Operational / Demo mode or in the Test Mode (also known as
“
HCI Pass-Through
”
mode) that supports Direct Test Mode (DTM) commands for controlling the radio. Placing the
lower jumper towards the right (green arrow) places the board in a Bluetooth Smart operational mode or
“
BLE
”
where various demos can be run. (The specific type of demo is selected by the position of the jumper on the top
row of J19). Placing the jumper towards the left (yellow arrow) places the board in the Test Mode where HCI
commands can be directly passed to the BT4 Radio IP via the SoC Host UART connector J14.
Figure 3.3.4 - Demo/FW Jumper
The top row of pins determine if the board powers-up as a Sensor Demo or as a Beacon Demo as shown in the
picture above. (As stated previously, the lower jumper must be in the
“
BLE
”
FW position). Placing the jumper
towards the left (Orange arrow) will place the board in Beacon mode whereas placing the jumper on the right side
(Red arrow) places the board into Sensor mode. The position of the jumper on the top row is not relevant if the
lower jumper is set to Test or
“
HCI
”
FW mode.
