Overview

The TiWi-R2 is EOL. The TiWi-BLE is the footprint and electrically compatible module that should be used in place of the TiWi-R2. The TiWi-BLE adds Bluetooth® Low Energy (BLE) functionality in addition to WiFi and Bluetooth®.

The TiWi-R2 Bluetooth® and WiFi module is a high performance 2.4 GHz IEEE 802.11 b/g/n Bluetooth®2.1+EDR radio in a cost effective, pre-certified footprint.

The module realizes the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over a SDIO interface.

The module also provides a Bluetooth® platform through the HCI transport layer. Both WLAN and Bluetooth® share the same antenna port.

FAQ

What is Laird Connectivity's product lifecycle EOL and PCN policy?

Laird Connectivity is committed to the long-term supply of all its standard embedded wireless modules and packaged products. Laird Connectivity’s products are specifically designed to meet the needs of the industrial and medical markets, which typically require 7 – 10 years product lifecycle. Although Laird Connectivity can’t guarantee that a component used in our products will not be obsoleted and cannot be reasonably substituted, Laird Connectivity can assure customers we will continue to sell our product when we have customer demand and can obtain the necessary components to build our products.

View our full policy here. 

The performance of my TiWi-R2 Module is not matching the published specs in the datasheet. What is wrong?

The ini file in your OS/Driver likely does not have the correct parameters. It is important that you update this in your OS/Driver by following the instructions in the TiWi Family INI Radio Parameter User Guide available on the TiWi-R2 Module download page.

What Bluetooth® Profiles are supported by the TiWi-R2?

The Linux driver supports A2DP, HFP, HSP, OPP and FTP profiles.
The Win CE driver supports SDP, SSP, OPP, FTP, DUN, PAN et AD2P.

Was any SAR testing done on the TiWi-R2 Module?

Yes, the TiWi-R2 Module is certified as mobile device >20cm from the human body. Note that Laird Connectivity has completed a class 1 permissive change allowing the TiWi-R2 to fall under these certifications.

How do I use the FM Radio on the TiWi-R2 Module?

The FM radio is tested by TI at the WL1271 level, but not tested at the Module level by Laird Connectivity at the present time. Therefore Laird Connectivity assumes no liability for its operation. If this is a requirement for an application, please feel free to contact Laird Connectivity to discuss. Information on using the FM radio (again at a customers own risk) can be obtained from TI. For example see TI OMAP Wiki.

Where can I get a datasheet for the WL1271?

The datasheet for the WL1271 is not public, and can only be obtained under NDA to customers through TI. Enough information is presented in the TiWi-R2 datasheet for most applications. Contact your local TI Sales Representative if you feel it is necessary to obtain the datasheet.

Is the TiWi-R2 obsolete?

No, the TiWi-R2 still in production, and there are no plans to discontinue it. Any new designs should use the TiWi-BLE or TiWi5 Modules. Both of these modules support additional features.

What antennas can I use with the module?

The answer to this question depends on if you plan on using the modular certification of the module. If you want to use the modular certification you need to use one of the antennas that the module was certified with. Consult the datasheet, or product webpage to determine which antennas the module was certified with. If none of the certified antennas meet your requirements, another antenna may be used, however the modular certification will NOT be valid. The new antenna will need to be tested for EMC compliance. Contact Laird Connectivity’s EMC Test Services to learn more about this process and how we can help.

Can I substitute antennas? For example can I use another dipole antenna instead of the exact model a module was certified with?

Yes, this is possible if:

  1. The peak gain of the alternate antenna is less than or equal to the original antenna, and
  2. The antennas are the same type.

There are some cases that are not black and white. It is the customer's responsibility to collect and retain the appropriate and accurate test data traceable to NIST standards for the alternate antenna. Please contact Laird Connectivity to discuss any questions.

Where can I get the command set/interface for WLAN and Bluetooth?

There is no published command set for either radio. The only interface is through the drivers built into the OS. The commands would have to be extracted, or reverse engineered from there.

Is there a way to retrieve the serial number(s) from the TiWi-R2, TiWi-BLE, and TiWi5 programmatically?

The Serial Number is not stored on these modules, it's only displayed on the product label. Recently a database was added to provide MAC address to Serial Number correlation. MAC to SN correlation can be requested via our support.
