In Internet of Things applications, the process of successfully connecting devices, the role of connectivity is crucial, and the scope of choice is also very wide: such as Wi-Fi, Bluetooth Low Energy (BLE), RFID, NFC, and so on. According to market share estimates, 60% of wireless devices will use Bluetooth before 2021, while low-power Bluetooth (BLE) will be used in 16% of devices. Most of the growth will occur in applications such as smart homes, beacons, connected homes, and wearable devices. In order to facilitate the selection of engineers BLE Bluetooth module, this Xiaobian to introduce the BLE Bluetooth module selection points and BLE Bluetooth module selection in the application of some parameters to be noted.
In the early stage of BLE Bluetooth module selection, it is necessary to understand the application scenarios and the functions that need to be implemented (application block diagrams), as well as the interfaces (master and slave devices, functions) that can be provided during function implementation, considering the power supply, size, and receiving sensitivity of the module. , transmit power, Flash, RAM, power consumption (broadcast, continuous transmission, deep sleep, standby status), connection distance, interface, antenna, cost performance, etc.
According to the Bluetooth standard, the BLE Bluetooth module of SKYLAB is roughly divided into a BLE4.0 module, a BLE4.2 module, and a BLE5.0 module, wherein the BLE5.0 module can support the Bluetooth Mesh technology; if the Bluetooth solution requires support of the master-slave one Bluetooth module, you can choose BLE4.0 module SKB360 or BLE5.0 module SKB369, if you want to implement Mesh networking applications, then give priority to Bluetooth Mesh technology Bluetooth 5.0 module.
BLE Bluetooth module selection parameters:
BLE Bluetooth module
Connection distance: According to the distance, the distance is selected according to the distance in the actual application of the Bluetooth solution to determine which BLE Bluetooth module is more able to meet the data transmission requirements.
Communication interface: The module product itself is to reduce the time to market, and in order to facilitate the use of the Bluetooth module, the existing BLE Bluetooth module provides a flexible hardware interface, supports UART/SPI/GPIO/I2C/I2S/PWM interface, the user can Start with the actual needs of the Bluetooth solution.
BLE Bluetooth module control application
Work mode: BLE Bluetooth is generally divided into master, slave, master/slave, master/slave, and a master can communicate with up to 7 slaves at the moment, supporting peer-to-peer communication. On the basis of supporting Bluetooth Mesh technology, it can achieve Many-to-many signal transmission modes can meet more connection requirements.
Power consumption: BLE Bluetooth module itself is known for low power consumption, but because it has a variety of working states: broadcast (100ms interval), continuous transmission (20ms interval), deep sleep (μA), standby state (μA); various states The power consumption value is also different. This requires engineers to determine according to the actual Bluetooth solution.
BLE Bluetooth module
Currently, SKYLAB's BLE Bluetooth module is mainly based on the Nordic nRF51822 chip Bluetooth module SKB360, SKB360I, SKB361, SKB362 and Nordic nRF52832 chip-based SKB369 and other low-power Bluetooth modules. Can be used in interactive entertainment devices: remote control, 3D glasses, game controllers; personal area networks: health/fitness sensors and monitors, medical equipment, keychains+watches, remote control toys, Bluetooth beacons, Bluetooth gateways, indoor positioning, Mesh Light control.
