TiWi-R2

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.

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

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

The FM radio is tested by TI at the WL1271 level, but not tested at the Module level by Ezurio at the present time. Therefore Ezurio assumes no liability for its operation. If this is a requirement for an application, please feel free to contact Ezurio 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.

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.

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.

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 Ezurio's EMC Test Services to learn more about this process and how we can help.

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 Ezurio to discuss any questions.

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.

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.
