If SIO_18 and SIO_19 are needed elsewhere, the LEDs can be disconnected by micro-DIP switch CON15. Physical
micro-DIP switch body has text “ON” on the closed side.
The buttons have no external pull-up resistor, so to use the buttons the SIO_16 and SIO_17 pins must be configured
as an input with internal pull-up resistor. Example: A
smart
BASIC line that configures the pull-up. For further details
see file “btn.button.led.test.sb” in the
smart
BASIC sample application library on BL600 product pages at
http://lairdtech.com/Products/Embedded-Wireless-Solutions/Bluetooth-Radio-Modules/BL600-Series/
rc = GPIOSETFUNC(16,1,4):
'//sets sio16 (Button0) as a digital in, strong pull up
rc = GPIOSETFUNC(17,1,1):
'//sets sio17 (Button1) as a digital in weak, pull down
The LEDs are active high, meaning that writing a logical one (“1”) to the output pin illuminates the LED.
One example of when push buttons can be used is when a
smart
BASIC application is written to simulate a generic
data profile. Push buttons can then be pressed to increment or decrement, such as a heart rate.

Current Consumption Measurement
A removable jumper (CON1) is provided to break the power supply line directly to the module (if SB9 is cut), allowing
you to measure current consumption. For normal operation, CON1 must be fitted.
IMPORTANT: To achieve the optimal power consumption of the BL600 series module on the development board,
see the “LowPower.SB” file in the
smart
BASIC sample application library on BL600 product pages at
http://lairdtech.com/Products/Embedded-Wireless-Solutions/Bluetooth-Radio-Modules/BL600-Series/
Note: This only measures the current consumption of the BL600 series module ONLY.
