Connect two Arduino Mega 2560 + SeeedBLEShields

The main board we used is Arduino UNO, and we use D2 and D3 as the software serial pins, but if using Mega with BLE shield, D2 and D3 can't be regarded as the software serial pins. See http://arduino.cc/en/Reference/SoftwareSerial , so maybe you can use 10 and 11 as the software serial pins, meantime, you need two jumper wires to connect BLE_TX (BLE_RX) to D10 (D11). At the same time, the code need to be modified:

Quote:

#define RxD 10
#define TxD 11

By the way, Arduino UNO has something differences with Mega, you can refer to http://www.Arduino.cc to search more information. Good luck.
