[Introduction]：E105-BS21X BLE Spark module is a serial port to SLE (SparkLink Low Energy) module based on SparkLink protocol version 1.0 and IPEX antenna interface. It has the characteristics of small size, low power consumption, long transmission distance, fast transmission speed, strong anti-interference ability, and low latency. It works in the 2.4GHz frequency band with a maximum RF transmission power of 6dBm. The SLE module uses universal AT commands, which is easy and fast to operate. The module can be widely used in smart wearables, home automation, smart home appliances, industrial Internet, smart control and other fields.
