Itead Bluetooth Shield - Master-Slave

Itead Bluetooth Shield - Master-Slave

The Bluetooth Shield integrates a HC-05 Serial Bluetooth module. It can be easily used with Arduino for transparent wireless serial communication. You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port).

The Bluetooth Shield integrates a Serial Bluetooth module. It can be easily used with Arduino/Iteaduino for transparent wireless serial communication. You can choose two pins from Arduino D0 to D7 as Software Serial Ports to communicate with Bluetooth Shield (D0 and D1 is Hardware Serial Port).

• Default PINCODE:”1234”A full set of configuration commands
• On board PCB antenna
• FCC ID certificated

The Missing BT Shield Datasheet

The official ITead Studio BT Shield v2.2 Datasheet is missing lots of information (at least I was confused). So this web page is my attempt to summarize the missing bits.

Upload Program To Arduino With BT Shield

The BT shield v2.2 use the same Bluetooth module as Iteaduino BT, we can hack it and make it a wireless programmer for Arduino as well. Here we take a Iteaduino with BT shield as a example, to show you how to upload the program to Arduino via Bluetooth.
