We making a project with Arduino at school.
One of the steps of this Project is: Connect two Arduino using two pieces of bluetooth RN42 (wireless connection between two bluetooths).
We used this link to do so : https://learn.sparkfun.com/tutorials/us ... esmirf/all
Now, when we disconnect from the computer and connect again Arduino, we should once again make a wireless connection between these two bluetooth.
we want to do that the bluetooths will be with auto detect.
So my question is what should I do to make an automatically connection between the bluetooths ? What commands we need to add in Arduino software ?
Many thanks in advance !
