clock source
Connect the jumper J5001 pins
with 0Ω resistor
to set the Bluetooth clock to
an external clock source, as shown below.
Bluetooth power input
Connect the jumper J5002 pins
with 0Ω resistor
to set the Bluetooth main
power source to VBT, as shown below.
Connect the jumper J5002 pins
with 0Ω resistor
to set the Bluetooth main
power source to VIO18, as shown below.
Bluetooth antenna
path
Connect the jumper J5003 pins
with 0Ω resistor
to select the antenna signal
uplink and downlink paths on an onboard antenna, as shown below.
Connect the jumper J5003 pins
with 0Ω resistor
to select the antenna signal
uplink and downlink path using SMA connector, as shown below.
Bluetooth I/O power
input
Connect the jumper J5004 pins
with 0Ω resistor
to set the Bluetooth I/O power
source to VBT, as shown below.
Connect the jumper J5004 pins
with 0Ω resistor
to set the Bluetooth I/O power
source to VIO18, as shown below.
Mount the 0Ω
resistor R5005 and disconnect the jumper J5004
with 0Ω
resistor to set the Bluetooth main power source to external buck LDO for low
power consumption.

Debugging
To enable debugging on the LinkIt 2523 HDK, activate the JTAG interface using Easy PinMux Tool. Switch from the
camera operation mode to debugging mode using JTAG interface by replacing the output pins in a range from GPIO
24 to GPIO 28 in Easy PinMux Tool from camera function to JTAG interface. The debugging log can be captured
