Introduction to Bluetooth sphygmomanometer module:

The Bluetooth sphygmomanometer module XZ-BLE01 is an industrial grade BLE single-chip solution developed by Shenzhen Xinzhi Technology Co., Ltd. for health electronic measurement equipment. The module integrates a high-performance and low-power 32-bit microprocessor, with built-in Bluetooth 4.2 low-power module and RF module. BLE chip has built its own "protocol stack", greatly optimizing compatibility and connection stability
