I plugged in my “Grove - Serial Bluetooth” to “Arduino Uno” and it works properly.
After that, i connected to the “Grove - Serial Bluetooth” via my Galaxy smart-phone and sending some data to Adruino form phone. Everything is fine.
But! Here is a question.
When i switching off my Smart-phone and turned it on again, or going to “Out of Range” bluetooth and comeback, I can’t establish bluetooth connection with “Grove - Serial Bluetooth” again. And nothing helps me!
The one way is to press “reset button” on Arduino Uno board! Pair may device again and send some data from a start.
The idea is to Not manage Arduino board by hands at all!. Only power on and sending some data there.
Can anyone help me? Please. Seems i “dig” all the Internet and didn’t find the answer.
