Has anyone successfully used the D0/D1 pins for RX/TX on this shield?
I note the default pins are D2/D3 but I also note the quick start guide states:
I am considering the D0/D1 pins in lieu of D2/D3 but I would like to know more about using these pins for Bluetooth and in particular if doing so conflicts with the USB serial connection in any practical way.There's one other thing to keep in mind. Pins D2 and D3 do not have hardware serial port features like pins D0 & D1. D0 & D1 are the special pins which are connected to the USB/Serial interface on the Arduino. This means you can't use commands like Serial.print(). You have to use a "Software Serial" feature on the Arduino.
For interest sake my project is based on the Etherten with Sensor shield to collect data (A0-A3), RTC module for obvious purposes (A4/A5), RFID door shield to enable/isolate a circuit (D2/D3/D5) and Bluetooth shield (hopefully D0/D1) to download data to Android devices. This project uses every last pin on the board if I have it correctly (including the easter egg pins A6/A7 which are to be used for sensor inputs).
