The TiWi-uB1 Bluetooth Smart module is a low-power 2.4 GHz Bluetooth 4.0 (BLE) System-on-Chip in a cost effective, pre-certified footprint. This module comes ships with no firmware in the embedded flash. Applications can be developed and loaded into the integrated microcontroller, and function without the need for an external processor.
The Bluetooth® Smart TiWi-uB1 module with System-on-Chip (SoC) does not come flashed with any firmware. The user is required to flash the desired application into the module. A hex file for the HostTestApp (v1.3.2) with FREQTUNE set to 0x07 is available for download.
Any firmware that runs on the TiWi-uB1 module should set the FREQTUNE register to a value of 0x07. This ensures the module will be on frequency during Bluetooth operation.
The TiWi-uB1 EM board demo provides several custom GATT profiles showcasing the flexibility of the TiWi-uB1 module. The demo showcases battery, temperature sensor, GPIO, and range test profiles allowing for an easy performance evaluation of the module.
TiWi-uB1 is certified with these Antennas
FAQsClick to view frequently asked questions.
A 32 kHz crystal is required in applications that use power savings, to maintain the connection timing required by BLE. If your application is line powered and does not use power savings, the timing is maintained by the 32 MHz crystal, and hence no 32 kHz crystal is required.
The TiWi-uB1 is a single mode Bluetooth Smart module, that supports Bluetooth Low Energy (BLE) only.
The TiWi-uB1 module is a System-On-Chip (SOC), that has an integrated microcontroller that can be used for application development.
The TiWi-uB1 module can be used in conjunction with an external host processor or microcontroller, using the HCI command protocol over a UART or SPI interface.
The TiWi-uB1 module is certified with an on module PCB trace antenna. Additionally the module is also 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. Note that the correct model of module needs to be ordered based on the antenna option being used (PCB Trace: 450-0103, Off Module: 450-0106). Consult the Antenna Design Guide for details on implementing the TiWi-uB1 module into your design with one of the above certified antenna options.
Yes, the module can be used with an external host. LSR does not provide any out-of-the-box firmware for the module that will allow this mode of operation. There are some great starter examples provided by TI here: Using the CC254x with an external host

TI BLE Wiki
The TI BLE stack provides many examples for rapid development of a BLE product. See the TI BLE wiki for more information. For development, IAR Embedded Workbench 8051 is required.
RF Testing Guide
This wiki page from TI explains in detail the different test modes supported by the TiWi-uB1. 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.
