Bluetooth LE for Arduino

[LinearAlegbruh]

Is it possible to do Arduino to Arduino communication with the Bluetooth LE shield?
If not can you recommend a similar product that would satisfy my requirement?

I want to use the module to send data wirelessly between two arduinos
- GPS data
- Image data
- Etc.

Thank you!

Went through the AT commands. There is no documentation on how to configure these Bluetooth shields as master or slave. Hope Team Adafruit will answer your question and clarify this matter.

No.

Bluetooth splits devices into 'central' and 'peripheral' categories. Central devices initiate and control all data connections. Peripherals advertise their presence, but otherwise sit and wait for a central to tell them what to do. That arrangement puts most of the cost and complexity in the central device, letting peripherals be smaller, lower power, less expensive, and so on.

The BLE Shield only works as a peripheral. With minor exceptions at the protocol level, peripherals don't even know that other peripherals exist.

In general, Bluetooth has no concept of peer-to-peer communication between devices. It treats BLE peripherals more or less as hardware data structures.

If you want peer-to-peer communication between microcontrollers, packet radio is a much simpler choice:
