The following is the meaning of the fields:
• Key = An identifier of the pin used in commands that reference it.
• Property: 0 = GPIO, 1 = IRQ, 2 = Tamper detect, 3 = line power detect, 4 = advertising enable, 5 = uart TX, 6 = uart RX.
• Pin = The Nordic pin designation.
• Is enabled = Boolean value . Is the pin enabled.
• Is fixed = Boolean. It is an actual physical pin.
• Type: 0 = input, 1 = output
• Set state: High or low if output.
• Read State: High or low if input.
• Is active high: Boolean. True = a high on the pin is the “exception” or “alert” condition for the input.
• ISR Received.
• Description: A string description of the GPIO purpose.
The output of a module to “AT+GPIOLIST=0” with none of the GPIO reserved yet is shown below. This shows all inputs available.
