TRBLU23-00200 Bluetooth Intelligent Serial Module

Not Recommended for New Design (NRND)


The Bluetooth Intelligent Serial Module is specifically designed for applications where robust short range connectivity is required. This particular module provides a reliable Bluetooth connection that exceeds all requirements in terms of performance. The excellent range of up to 300 meters with very low power consumption of less than 36 mA makes this module a true class leader.

Note: Some variants of the TRBLU23 and related DVK and SDK variants have reached end of production and are available on a limited basis only. Find the End of Life Announcement in the Documentation tab below. Only the following part numbers are affected: - TRBLU23-00300 - TRBLU24-00100 - TRBLU2400100-NA

CSR Bluesuite Bluetest3 crashes when trying to select the transport.

Bluesuite is a very old program supplied by CSR for testing and configuration of its legacy Bluetooth modules. Bluesuite Bluetest3 is often used for RF testing where the DUT is put into BCSP mode before running Blutest3.

If Bluetest3 crashes with an "array" error you may have a conflict or issue with your .net installation. You may be able to fix the issue by removing all versions of .net but please speak to your IT department first as this may cause issues with other software.
