I want to read GPIO status through HCI commands. Firstly, I tried to use BlueTool(v22.214.171.124) 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(p1) to J10(VDDIO 1.8v).
How can I read GPIO status through HCI UART?
As my colleague advised in the other thread, you cannot do this via HCI uart as our solution does not allow it to, let alone using Bluetool.
