| range (bigger distance) is governed by Bluetooth Class I vs. II, etc. |

Hello DZairo,
I just finished my first Bluetooth4.0 (=BLE=BluetoothLowEnergy) product using Bluegiga BLE112 modules. I programmed them in a script language, using the module as main processor.
Please mind that BLE can NOT communicate with earlier Bluetooth versions. You need to communicate between 2 BLE modules or use a BLE and on the other side a modules that can handle BLE and 'old'bluetooth.
But if your setup is just to communicate between BLE and BLE it works great, has very little power consumption and range is I think similar. |
