Studio Bluetooth Forum Discussions

I am supporting a customer using the CYW20704 and need some help answering some questions.

1. What is the difference between the A1 and A2 revisions of the silicon. Customer has both and would like to know what the errata on the A1 was that was fixed on A2.

2. Do we have any information on the Host Wake Signal operation in USB mode?

3. Do we have any information on the electrical specification for the Host Wake signal. is it open collector?

4. The customer has followed our reference design, which should allow them to inherit the Bluetooth QID. Do they inherit the certification (FCC CE etc) or what do they need to do to simplify this process?

Thanks

Hi, i use the demo board of CYW92070xV3_EVAL for near one month. And it now doesn't work smoothly. It often downloads failed and gives a hint that the CYW20706 was not detected. And i have checked the power supply and the driver, and they are all normal. Only when i reinstall the WICED-Studio-5.0, the demo board can then work.  But after several hours,it will come the same question. Can you help to analyse the problem? Thanks.

When I installed WICED 5.2.0.22, there was an error "Not enough free disk space on selected folder location. Selected location has only 1M space available, press OK to select  a different location where there is at least 1000 M space available." However, the available space of my selected location is more than 50 G. I always tried the root directory of C disk, this error also happened.

One of my collegue, he successfully installed this SDK, but I don't know there is any difference between his PC with Mine.

Is there something wrong with this SDK or there is some confilct with other software?@
