I want to get started with Bluetooth 4.0 / Bluetooth Low Energy / BLE.
I know it's different from a normal Bluetooth.
Currently I'm using BlueSmirf Bluetooth 2.1 module, UART interface and SPP profile.
I have a simple operation sending a string to arduino. Up to 512 byte/second. Since I'm using BlueSMirft BT module, it's easy and everything is transparent.
It's seems it's not easy to do this in BT4.
I just want to get the basic idea how difficult it's to learn BT 4.0 before I buy the development kit. Not cheap, $350+.
- Do you have a sample code on how to setup and send a simple string using BT4?
- Bluetooth low energy technology supports very short data packets (8 octet minimum up to 27 octets maximum) that are transferred at 1 Mbps. http://www.bluetooth.com/Pages/low-energy-tech-info.aspx With this limitation, can I send data 512 bytes / second?
