Hi-link BLE5.0 Wireless Bluetooth Module HLK-B26 Master-Slave Integrated Serial Port Transmission Support APP Low Power Consumption HLK-B26 --EngrWorld

HLK-B26 is a BLE5.0 master-slave integrated Bluetooth serial port transmission module developed and produced by Hi-link Electronics. Various devices with serial ports can use Bluetooth wireless data transmission and reception simply and quickly through this module.

This product can be set to be used as a Bluetooth slave or host device. The host mode supports connecting one slave, and the slave mode supports connecting up to one host.

By using the serial Bluetooth bidirectional transmission function of this module, users do not need to understand the complex Bluetooth protocol stack. They only need to connect the customer's device or MCU's serial port to this module, and the module will automatically complete the bidirectional data forwarding between the serial port and Bluetooth (GATT), which is like a bridge between the user's MCU serial port and Bluetooth device, adding Bluetooth wireless transmission function to the user's serial device. Supports AT command mode, which allows for querying or setting basic parameters of the module, such as device name, serial port baud rate, etc., through serial port AT commands. This module provides rich testing tools and user documentation, including a mobile app demo, making it easy for users to quickly become familiar with and apply this module.

The schematic diagram of the Bluetooth serial port transparent function is as follows:
