Introduce:   BLE5101 is a Bluetooth-to-serial transceiver module based on Bluetooth protocol version 5.1, with coexisting master and slave roles, small size, low power consumption, and a working signal frequency band of 2.4GHz. The BLE5101 module is developed by Shenzhen Siwei Wireless Technology Co., Ltd. The module supports the coexistence of master and slave roles, can connect the host and slave at the same time, and can flexibly set the number of master-slave connections, up to 20 connections. Data transmission with a maximum baud rate of 115200bps is supported. In addition, BLE5101 also has BLE Mesh function, which can be used with other modules to achieve mesh networking. The module uses AT commands to set parameters, and the operation is simple and easy to use. The module can be widely used in smart wear, smart home, automobile, lighting, intelligent automatic data collection, intelligent control, wireless sensing, electronic tags and other scenarios. BLE5101 Bluetooth to serial transceiver module is produced and tested strictly using lead-free process, and complies with RoHS and Reach standards.     Feature:  Support Bluetooth 5.1 protocol.  Support coexistence of master and slave roles, can connect multiple masters and slaves at the same time, up to 20 connections.  Support two working modes: configuration and transparent transmission.  Support over-the-air upgrade (OTA DFU).  Support a variety of serial port parameter configuration.  Support automatic broadcast, scan, connect.  Supports two connection methods, manual connection and automatic connection, which can be flexibly configured and compatible with similar BLE products.  MTU is up to 247 bytes.  Supports custom 16-bit UUID, including one Service uuid and two Characteristicuuid, which can be flexibly configured and compatible with similar BLE products.  Maximum communication distance 150m (10dBm, 2mbps).  Support custom modification of local macaddress.  Support macaddress binding, bind up to 8 devices (regardless of master and slave).  Support low power sleep.     Application:  Wireless meter reading wireless sensing.  Smart home.  Industrial remote control, telemetry.  Smart buildings, smart buildings.  Automated data collection.  Health sensor.  Smart wearable device.  Smart robot.  Wireless sensing.  Electronic label.  Intelligent control.     Package includes:  1 x Wireless module
