Hi,
Sorry i am a beginner into bluetooth and arduino field but im currently looking into possibilities of connecting a HC-05 (ZS-040) bluetooth module to a phone (android) automatically when within range.
I am also creating an app (via MIT app inventor2) to turn a LED on/off via the app once the phone has automatically connected to the HC-05. Is the HC-05 right module for this ?
I am aware of the 'list picker' option via MIT app inventor to connect to the HC-05, however is there an alternative approach for an automatic connection to the phone ? What is the best possible approach for this kind of scenario ?
Might I also add that simple pairing between the phone and the hc-05 didn't warrant an automatic connection. It simply allowed the device to be detected via the "list picker" on the app.
Regards Kav
