  1. Does the TiWi-uB2 module support both Classic Bluetooth® and Bluetooth® Low Energy (BLE).

    Yes the TiWi-uB2 module is a dual mode Bluetooth® Smart Ready device, that supports both Classic and BLE.

  2. Can I develop my application directly on the TiWi-uB2 module?

    The TiWi-uB2 module requires a host processor or microcontroller to be used in conjunction with the module. The upper layers of the Bluetooth® or BLE stack runs on the host processor/microcontroller along with the application..

  3. Which antennas are certified with the TiWi-uB2 module?

    The TiWi-uB2 module is certified with the LSR 2.4 GHz Dipole and 2.4 GHz Waterproof Dipole antennas, used in conjunction with any of our U.FL to Reverse Polarity SMA cables. Additionally the module is also certified with an off module Johanson Technology 2450AT43B100 chip antenna. Consult the Antenna Design Guide for details on implementing the TiWi-uB2 module into your design with one of the above certified antenna options.

RF Testing Guide

This wiki page from TI explains in detail the different test modes supported by the TiWi-uB2. These test modes can be used for RF evaluation and production testing. In addition the LSR Bluetooth® Eval Tool provides the user easy access to these commands via a PC GUI.  If using a PC to control the module is not an option, hcitool in Linux can be used to send test commands directly to the module.

Software & Firmware

See the TI CC256x wiki for loads of information and software examples.
