Dear Sirs and Madams!

I have PCB with BCM20730/CYW20730 with LED diode connected to it via P4:

Now, I am trying to control this LED from BlueTool using HCI Control -> 0: Vendor Specific Commands -> GPIO_Config_and_Write:

Now:

  1. From BCM20730/CYW20730 datasheet I can see it has more GPIO ports than 8 (addressable from BlueTool). Why are only 8 addressable from BlueTool?
  2. As we can see from schematic, If I set P4 (BlueTool GPIO_Pin_Number set to 4), to HIGH, why LED does not turn on? The hardware has been verified, from custom firmware I can control the LED, what I cannot it control from BlueTool?
  3. What does checkable parameter Auxiliary_GPIO_Control means?
  4. What are Pad_Config parameters Sel0, Sel1 and Hysteresis mean?
  5. Finally, can someone provide me full BlueTool manual with commands (and their parameter(s)) descriptions?

The communication channel has been setup properly, becuase I can successfully, for instance, reset the BCM20730 on PCB:

Sincerely,

Hi marko.frelih_3844636,

CYW20730 is not a broad-market chip and is not supported here on Community. Please get in touch with your local Cypress Sales team or FAE. They will help you for getting support on your query.
