Connection distance: select according to the distance, and determine which BLE Bluetooth module can better meet the data transmission requirements according to the distance in the actual application of the Bluetooth scheme.
Communication interface: The module product itself is intended to reduce the product launch cycle. In order to facilitate the use of Bluetooth modules, the existing BLE Bluetooth modules provide flexible hardware interfaces and support UART/SPI/GPIO/I²C/I²S/PWM interface, users can start according to the actual needs of Bluetooth solutions.
BLE Bluetooth module control application
Working mode: BLE Bluetooth is generally divided into master, slave, master-slave integration/master-slave connection. At present, a host can communicate with up to seven slaves, supporting point-to-point communication. Based on the support of Bluetooth Mesh technology, it can achieve a “many to many” signal transmission mode, which can meet more connection requirements.
Power consumption: BLE Bluetooth module itself is known for its low power consumption, but it has a variety of working states: broadcast (100ms interval), continuous transmission (20ms interval), deep sleep(μA), standby mode(μA)； The power consumption value in each state is different, which requires engineers to determine according to the actual Bluetooth scheme.
