E104-BT40 module is a serial to dual-mode Bluetooth slave module based on Bluetooth 4.2 + 3.0 version, namely low power consumption Bluetooth BLE and classic Bluetooth SPP Profile, which can freely switch between BLE and Classic Bluetooth, working at 2.4GHz. The E104-BT40 module uses general AT commands to set parameters, and the operation is simple and fast. The module only supports the Bluetooth slave role. Through this module, traditional low-end serial devices or MCU-controlled devices can performwirelessdatatransmission. It is a low cost, simple and reliable data transmission module.
