Hi,
your programs looks really nice, I would really like to buy the PRO version, but I have same problem as skydge has.
It can't be paired with bluetooth.
"connection is established, but device does not reply: time out error: no response"
Can you help me?
I tried using many boards /UNO, Nano/, many bluetooth modules /HC-05/, I also tried it on both KitKat and Lollipop devices
Pairing doesn't work even if I connect only VCC and GND, but other apps like Ardurdroid etc. can connect without problems.
Thank you for answer.
