I’ve picked up the Shield in order to send/receive data from either a Windows PC or Android device. I’ve followed: seeedstudio.com/wiki/Bluetoo … _Windows_7 as best as I can but can’t seem to get the Arduino/Bluetooth to receive data at all. I’m able to output data and read it on the pc/phone using BlueToothSerial.prin() in my code just fine. However I may have had the TX/RX pins connected backwards.
At first I was using BT_TX > RX(D6) and BT_RX > TX(D7) With this setup I can receive data but not send from PC/Phone. After looking at the wiki again and again, I noticed I may have it backwards so I flipped to: BT_TX > RX(D0) and BT_RX > TX(D1) and now my code doesn’t upload while the Shield is connected, I get avrdude out of sync error.
So I’m here for any advice, tips, suggestions because I’ve been working with this module for a day or two now and I can’t get it to cooperate. Also do I need to use the jumpers to make the connections to the digital pins or just make jumper wires?
Thanks in advance,
