    GPIO2 is already been internal pulled up

     In transparent-transmission on power-up mode, GPIO2 will indicate the status of module. The module has connected a led to this pin. Users can get the status of the module by observing LED. Besides, you may connect GPIO2 to the external MCU.

     LED indication when module works in power-on transparent transmission mode:

    Intermittent double flash:cannot connect to AP access point.

    Intermittent single flash:connect to AP access point, but cannot connect to TCP server.

    Quench:connect to AP access point and TCP server.
