Hi there people this is JUST FOR ANDROID and for the BLE only module ( not the more elaborately documented LTE )( since there seems to be an IOS example) but sadly, for the rest of us we have no such basic examples. All I am trying to figure out is a) what exactly the gpio pins are ( in terms of which is input/output and which are voltage lines(powerin gnd)) b) and finally how to use my ANDROID phone, and develop a simple code for on/off led.
Also was wondering how come in your examples the led requires no resistor ( which is strange to me seen as the back current of most MCUs will burn an 3.3v (3nano amps) in 4sec). Any examples that don’t use visual studio will be helpful. ( no C# language please) thanks!!.
