We ended up (like many others using BLE) with an RPC service built on top of GATT services and characteristics. What I'm using is a Python script running on the Raspberry Pi which collects the data and stores it…. The module implements only the peripheral role functionalities, while the central role ones are not included. With BLE, the old profiles are gone and replaced instead by the GATT, a very flexible (and power efficient) way to define and handle data transfer via the sharing and remote update of “characteristics”. Slave / Peripheral - the BLE device which accepts an incoming connection request after advertising GATT client - a device which accesses data on the remote GATT server via read, write, notify, or indicate operations. python ble_test. The nRF51 is a system-on-chip with a Cortex M0 and a BLE radio chip all in one. On paper, though, BLE’s HID over GATT is much better than the old bluetooth hid if it will work for you; lower power usage, lower latency, and a much more open ecosystem.
