Page 8: Description
The Cordio BT4 Module and Customer Evaluation Base Board is based upon the CORDIO™ BT4 Development SoC which is a low power, 40 pin 5 x5 mm QFN that contains the BT4 Radio IP plus an ARM Cortex M0+™ host MCU. -
Page 9: Features
The board is mbed enabled allowing the user to utilize mbed tools and example source code as well as Keil tools to develop custom FW for their ARM Cortex based SoC while it is still in development. It also supports drag-n-drop FW programming of the Module. -
Page 10: Hardware
Figure 3.1 - BT4 Customer Evaluation Board – Block Diagram Block Diagram The ARM Cordio BT4 Radio IP can be run in either a 1 volt or 3 volt mode/domain. The Cortex M0 Host processor and its memories within the SoC are run at 1.2 volts. Level shifters are provided on all I/O buses to take the SPI and I2C interfaces to 1.8 Volts and the UART and Serial Wire Debug lines to 3.3v. -
Page 11: Power Selection And Switches
We recommend all 3 of these switches be slid to the right (towards the edge of the board) in the “OFF” positions so that the batteries are not drained due to powering their respective on-board voltage regulators.

(located along the top right edge of the board) in the 1 volt mode by sliding the switch upwards. (See Section 3.2.33.2). With power still removed from the board, remove the jumper from J30 (located just above the ARM mbed logo). Attach your desired current measuring equipment across the two lower pins of the connector as shown below. The center pin, Pin 2 on the connector, is the downstream voltage supply rail to the BT4 SoC. - Page 23 3 Tx events. For more information on this connectable or “discoverable” stateplease refer to Section 3.5.2. This type of measurement can also be taken in 3 volt mode as described in the next section.

The common test set-up is depicted in the figure below. The DUT/EUT is controlled via the UART interface while RF measurements are received via a calibrated RF Coax cable, typically with an in-line 10db attenuator.

Page 26: Use Of Other Rf Analyzers
6.1.2 Use of other RF Analyzers As an alternate test method, ARM provides a Windows based Radio Control Tool, or “RCT” included in the BT4 Evaluation Kit. (See Section 6.1.3 below). The typical set-up for the RCT is depicted in the figure below. The PC is attached to the DUT (BT4 Eval Board) via a USB to UART cable as well as the USB to Mini-B USB cable, both provided in the kit. -
Page 27: Arm Radio Control Tool
6.1.3 ARM Radio Control Tool ARM’s Radio Control Tool (RCT) is a Windows/LabVIEW based utility that controls the BT4 Radio IP block via the BT4 Demonstration SoC’s Host UART port (J14). The tool can place the Radio in either continuous transmit mode or receive mode. -
