深圳市富微科创电子有限公司 Shenzhen Foxware Technology Co., Ltd I. Functions This module is a BLE Pass-through Module based on the Bluetooth Low Energy standard released by the Bluetooth SIG. This module can be controlled by the serial port and MODE_CTL pin, and be wirelessly controlled through the host. Users can develop standard low-power Bluetooth (BLE) products in a short period of time and don’t have to worry about complex Bluetooth protocol application software. After the connection is established through the serial port control, bidirectional data transmission can be realized between the BLE master and the slave. Function Overview: 1. Support pure pass-through mode and command mode: In pure pass-through mode, the data received by the serial port will be transmitted to the host as it is, and the data received from the host, it will be transmitted to the user MCU as it is. In command mode, the user MCU can configure and obtain the parameters of the module through corresponding commands. 2. Can be switched between pure pass-through mode and command mode through IO port, and can also be configured through the host; 3.Design of common serial port. The baud rate can be configured through the serial port or the host, which makes it easy to adapt different MCU resources but the default is 9600bps, with low-power data preservation; 4. The Bluetooth broadcast period and the Bluetooth connection interval can be configured through the serial port or the Host, which is easy for reasonable control of Bluetooth power consumption and low-power data preservation; 5. Configure the Bluetooth device name through the serial port or the Host to facilitate device differentiation in actual applications and low-power data preservation. 6. The Bluetooth pairing code can be configured through the serial port or the host, and can be set enabled or not; 7. Reset module through the serial port or the host 8. Factory reset can be restored through the serial port or the host; 9. The Bluetooth MAC address (physical address) of the module can be obtained through the serial port. 10. The Bluetooth transmit power of the module can be set through the serial port or the host to reasonably control the communication distance and the power consumption. 11. Support the simpliest development, that is, in the case of simple functional requirements, only need to connect to the serial port for product development. For example, the mode control pin will be kept in low level when no control is needed, saving the I/O resources of the MCU.
