Key points and pitfalls of GATT design, reconnection, and background operation.
This article explains the design points for developing applications that connect smartphones and devices using BLE (Bluetooth Low Energy). It covers aspects such as the division of GATT design, reconnection design based on disconnection, constraints of background operation, differences in permissions between iOS and Android, and the limitations of MTU. From the perspective of a company that also conducts embedded development on the device side, it introduces five examples of challenges encountered in real projects.
