IMPORTANT NOTES - PLEASE READ PRIOR TO CONTINUING
7173 S. Havana Street, Suite 600
Audio is currently supported on Channel 0 only.
The Bluetooth radio’s reset logic is active LOW for C40 and C46 BC04 BTver2.0 modules.
Unlike the old firmware the new parser design will not accept line feed <lf> after issuing a valid AT
Command only a carriage return <cr> shall be used.
To provide the best firmware architecture, design, and future profile support there is not 100%
code backwards compatibility in regards to certain AT Commands and responses.
firmware is targeted to CSR BC04 platforms. The firmware was developed and tested on BC02 and
BC04 platforms. The ATDI command response string no longer returns radio name. There is a
separate command to request a remote device name based on CSR’s newest design
implementation.
There is an error on Version F of the Eval Board. The two vias marked PIO6 and PIO7 are not
connected to their respective pins on the C40 module, only to the C46.
measurements from these pins you must measure directly from pins 3 and 4 of the radio. This will
be corrected in the next version.
Overall performance improvements from BC02 to BC04:
Maximum data throughput for a single point-to-point connection in fast data mode Master to Slave is:
231.2kBps and Slave to Master is: 188.2kBps

-
While in regular data mode (AT Command parser running) it is only 35Kbps.
Current consumption is 15% less.
Inquiry responses are much faster.
