I'm trying to work on a BTLE application using the BGM113 module, and yes there are thermometer examples and the like out there to run on an Android/iOS. However, I'm looking to develop a standalone C program on a linux laptop using bluez (linux's official bluetooth stack). For simple usage scenarios, the only differences are the socket type specified, the protocol family, and the addressing structure. By default, L2CAP connections provide reliable datagram-oriented connections with packets delivered in order, so the socket type is SOCK_SEQPACKET, and the protocol is BTPROTO_L2CAP. For example, it works well if you're working on a standalone device and you want to configure the device via a custom Bluetooth profile, or you have a device that speaks a standard protocol that your Linux machine doesn't yet support.
