Deskripsi Produk

Mini size data transmission module BLE4.2 serial to Bluetooth

HLK-B20 is an new low-consumption Bluetooth BLE 4.2 control module made by Hi-Link. This product is a Bluetooth-compliant module based on universal serial interface. It has built-in BLE 4.2 protocol stack, which can realize data conversion between user serial port and Bluetooth interface.

Our company develops and provides rich testing tools and use documents, and provides app demo for testing, so that users can quickly start to be familiar with and apply this module. Our company can also provide flexible and rich customized development services according to the specific needs of customers.

To ensure that all configuration procedures are correct, first reset the module to factory settings. Modules that are already in factory mode can skip this step. Provide 5V (1000mA) power supply to power on the module, wait for about 1 second, let the module start up. After the startup is completed, pull down the ES0 (PIN5) pin for more than 6S. When the LED corresponding to the STA is always on, it means that the module is restored the factory settings successfully, then release the ES0 pin, the system will automatically restart. The system is already in factory mode after rebooting.
