    P1_7 is reserved for this purpose and in case of BLE121LR it can only be used as an output controlling the external DCDC. Thus in BLE121LR P1_7 is named as DCDC CNTRL. The important differences between the carriers are shown in the Figure 4 (BLE112 and BLE113 carriers) and Figure 5 (BLE121LR carrier). Bluegiga Technologies Oy Page 7 of 20...

  • Page 9: Why The External Flash Chip Doesn't Work With Ble121Lr Carrier

    1.2.2 Minimizing the Current Consumption In all Carriers pin P1_4 is externally pulled down by the pull-down resistor in DKBLE. The purpose of this resistor is to avoid leakage when using the display. Note that any PIO’s configured as peripherals do not have internal pull-down or pull-up capability and thus, when left floating, they will require external pull-down resistor.

    2 Getting Started With DKBLE By default the modules delivered with the DKBLE have demonstration FW which prints the temperature to the display and starts automatically advertising. Several example applications are provided with the SDK package downloadable in the Bluegiga web pages.

  • Page 11: Using The On-Board Debugger To Program External Ble Devices

    The analog comparator of BLE112, BLE113 and BLE121LR is fixed to the pins P0_4 (-) and P0_5 (+). The pins overlap with the UART TX and RX signals in DKBLE. Thus to use the analog comparator the USB to UART converter must be turned off. Refer to Bluetooth Smart Software API Reference for details about the analog comparator configurations.
