Bluetooth 4.2 evaluation and prototyping platform

A USB-based Bluetooth development platform based around Toshiba Electronics Europe’s TC35678 BT 4.2 single-chip Bluetooth Low Energy (LE) controller has been announced.

The USB driver should automatically be detected by the Microsoft operating system once plugged into the port for the first time.

The idea is that the device can be used through the USB hub as a target platform within an Integrated Development Environment, controlled by the on-board USB J-LINK connected to the on-chip single-wire-debug interface.

Toshiba’s software tool, EasyStandAlone, will allow programming of the embedded flash memory from the PC side. Alternatively, a Graphical User Interface PC application should also work to enable access to the Bluetooth LSI via the on-board FTDI-UART connection for host mode applications running on the PC.

In both cases, Toshiba has said that the USB stick will work with its software development kit, which can be downloaded from the supplier’s developers website.

Toshiba has claims its TC35678FSG Bluetooth LE controller embedded within a PAN1760A module from Panasonic achieves ‘class-leading low current consumption’ and incorporates 256kB of built-in Flash ROM to store user programs and data for stand-alone operations.

Powered by the USB, the system can be configured via a series of simple jumpers. These jumpers are designed to offer flexibility, as they enable users to apply external control of the system reset or external power via a battery source.

Users should also be able to design and debug sophisticated interface structures, as all of the GPIO lines from the TC35678 are available on headers/jumpers.

Toshiba says that the board can be configured to be used in either host or standalone mode (no external host used in standalone mode) by setting GPIO lines during a reset operation. Furthermore, each of the three power modes are available and GPIO lines can be used for waking the system.
