Functional Description

The DKSB1013A breakout board from Digi-Key was created to give easy access to the PAN1555 Bluetooth module, which would otherwise be difficult to evaluate and prototype with. The DKSB1013A is pin and footprint compatible with XBee® modules from Digi International®, features two 8-position 0.1” headers spaced at 0.7” for use in a solderless breadboard, and has a 4-position 0.1” header located at the back of the PCB that contains the four necessary signals to create an SPP link: +VDC, Ground, Tx, and Rx. CTS and RTS are available on the 8-position and XBee® headers.

An optional LDO regulator on the bottom of the PCB (not included) can power the DKSB1013A from between 4VDC and 5.5VDC. 1uF 0805 ceramic capacitors provide input and output voltage stabilization for the regulator and are required to use the regulator.

About the PAN1555:

The PAN1555 with the Bluetooth Serial Port Profile (SPP) is a wireless drop-in serial cable replacement. It effortlessly creates a serial link between a Bluetooth enabled host devices such as PCs, smart phones, or tablets, and your embedded system based product. Alternatively, it can act as a Bluetooth host and connect (via AT commands) to other BT SPP devices in slave mode. The only local signals necessary to create either link type are Ground, Vdd, Tx, and Rx. CTS and RTS are also available for flow control.

The PAN1555 Bluetooth module is based on Cambridge Silicon Radio’s BlueCore6-ROM (BC06) and is controlled by a 32-bit STM32F103 ARM Cortex M3 microcontroller. Multiple Bluetooth profiles are available for the PAN1555 from Stollmann, including SPP, HSP, HFP and HDP (SPP is preinstalled). The module is fully Bluetooth qualified and FCC, CE, and IC certified. Optional interfaces available for custom firmware include SPI, USB, additional UARTs, ADC, JTAG, PCM, and GPIOs.

To get the device up and running, simply follow these steps:

  1. Connect the Ground and 3.3VDC lines to your power supply, and the Tx and Rx lines to your embedded host.
  2. Power on the module and begin the pairing process with your host device (PC, Android, etc.)
  3. The device name is BlueMod+P2x/G2 XX:XX where XX:XX is the last four characters of the MAC address of the PAN1555. (Example: 05:D3) The MAC address is seventh line of text on the metal shield of the PAN1555.
  4. If prompted, the Bluetooth pass code is 0000 (four zeros).
  5. Most operating systems will create a virtual COM port over Bluetooth.
  6. Begin serial data transmissions through the virtual COM port with your target device as if a serial cable is connected.

A Digi-Key Digi-Board (p/n: DKSB1013A) is available to evaluate or prototype with the PAN1555. The DKSB1013A breaks out all signals necessary to interface with the SPP UART and plugs into a solderless breadboard, a Digi® XBee® socket, or your prototype.
