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. | ||||||
