Product Introduction
HLK-B50 is a produced by Hi-link Electronics. It supports both BR/EDR various devices with serial ports can use receiving data easily and quickly through this module.
By using the serial Bluetooth bidirectional transmission function of this module. 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 . GATT and SPP can be connected simultaneously, which is like a bridge between the user's MCU serial port .
Supports AT commands, which can be used to query or set the basic parameters of the module, such as device name, serial port baud rate, etc. Supports Bluetooth BLE wireless configuration module parameters and OTA wireless upgrade module firmware;
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 module has abundant on-chip resources and external pins, which can provide flexible and in-depth software and hardware customization development services tailored to the specific needs of customers.
