RE: What is the difference between developing BLE custom GATT profiles and Bluetooth classic SPP?

Thanks for the answer. The similarity that I have in mind is that both SPP and BLE Gatt are good for sending data around. Sending sensor data would be a good application. I was wondering in what ways are the data characteristics that can be carried by BLE different from SPP.

I'm not sure if I understand your question correctly, but Bluetooth Low Energy (also known as BLE, Bluetooth Smart or Bluetooth 4.x) can be considered a completely new technology, very different from previous Bluetooth versions. As you say, BLE is designed for very low power consumption. The Serial Port Profile (SPP) is a profile based on BR/EDR (Basic Rate/Enhanced Data Rate introduced in Bluetooth V2.0). I'm not sure if there is a BLE equivalent of the profile out there, but you can check out the "UART/Serial Port Emulation over BLE" example in our SDK.
