We are pleased to announce that as of August 13, 2015, Qualcomm Global Trading Pte. Ltd., a subsidiary of Qualcomm Incorporated, has completed its acquisition of CSR plc. For more information, please see the press release .

CSR Synergy™

CSR Synergy™ provides an integrated host software solution for a wide spectrum of desirable wireless connectivity technologies.

CSR Synergy allows feature sets to be added without the usual integration and interoperability problems. CSR Synergy builds on the success of BCHS – the most widely used embedded Bluetooth® software stack in the world today. Like BCHS®, CSR Synergy has source code in ANSI C, is easily extendable and has a virtual OS for easy portability. With CSR Synergy, OEMs only have one solution to port, resulting in a smaller memory footprint and less resources required for the porting job than separate solutions. It is also easy to remove or add-in technologies to CSR Synergy.
