G-NiceRF 2Pcs BLE5.1 Master-slave Coexistence Low-power bluetooth 5.1 to Serial Port Transceiver Module BLE5101-T
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.
