    GPIO_Read command doesn't work in BlueTool on BCM20737.

      I want to read GPIO status through HCI commands. Firstly, I tried to use BlueTool(v1.9.6.2) to do this on BCM920737TAG-03. But I found two issues.

      1. GPIO pin number's range of "GPIO_Read" command is 0~31, but "GPIO_Config_and_Write" pin number range is 0~7.

      2. GPIO_Read(pin_number = 1) always return "Low" even I connected J7[1](p1) to J10[1](VDDIO 1.8v).

       

      How can I read GPIO status through HCI UART?
