3. راه اندازی و پیکربندی
The E104-BT51A module's parameters are configured using AT commands. This method provides a straightforward way to customize the module's behavior to suit specific application requirements.
3.1 حالت کار
The module supports two primary working modes:
- حالت پیکربندی: Used to set various parameters of the module, such as baud rate, broadcast interval, UUIDs, and other operational settings.
- حالت انتقال شفاف: Once configured, the module operates in this mode to transparently transmit serial data over Bluetooth Low Energy.
3.2 AT Command Interface
To enter configuration mode and send AT commands, connect the module's serial interface to a host device (e.g., microcontroller, PC via a USB-to-serial converter). Use a serial terminal program to send commands. Refer to the detailed AT command set documentation provided by EBYTE for specific commands and their syntax.

4. دستورالعمل های عملیاتی
After initial setup and configuration, the E104-BT51A module is ready for operation. The module primarily functions as a Bluetooth slave, awaiting connections from a master device.
4.1 انتقال داده ها
In transparent transmission mode, any data received via the serial port will be transmitted over the BLE connection, and any data received over BLE will be output through the serial port. Ensure the baud rate of the host device matches the configured baud rate of the module.
4.2 Broadcast Functionality
The module can be configured to broadcast specific data, including IBeacon or standard broadcast packets. This is useful for applications requiring device discovery or proximity sensing. Broadcast content and intervals are set via AT commands.
4.3 IO Port and Analog Functions
The module offers advanced functionalities such as IO port level output, PWM output with adjustable frequency and period, and ADC for analog quantity acquisition. These features can be controlled and monitored through specific AT commands, allowing for integration with various sensors and actuators.
