Hi, I'm new to Bluetooth programming, and I have some basic questions about the best approach to implement a fairly simple scenario. I have a small embedded device running Linux, and which supports Bluetooth 4.0. I'm also developing a mobile app that needs to exchange some data with the embedded device. The data consists of only a few JSON-encoded objects and is small in volume. The communication must happen bidirectionally, though. Those are pretty much the requirements. Now the questions: a) On the embedded side, do I need to program a small daemon using the DBUS-based Bluez API, or can I set up a special device and read/write to it as if it were a character device? b) The old interface [1] has been deprecated, right? (It's my understanding that only the new DBUS-based API should be used.) c) Is Bluetooth Classic or Bluetooth Low Energy better for this scenario? (I've read that BLE can dispense with pairing.) Thanks in advance for your time!
