Testing HC-05 / HM-10 bluetooth modules
Was supposed to be just testing HC-05 bluetooth module, but just discovered that Apple devices do not allow the regular bluetooth from HC-05, only BLE from newer HM-10 modules.
So, ordered some HM-10, should come tomorrow...
In the meantime, dug up an Android tablet and installed an app called "BT Robot Controller". This has some buttons to move robot forward and back and such. Every time you push a button, a character will appear in PST window using this code.

What I really want to do is use an app called "Mecanum Robot". This is in both apple and android stores. But, seems to only work with BLE
So, well guessing putting this on hold until HM-10 modules show up
