Bluetooth Dual Mode Module VS HC-05 Module

HC-05 Bluetooth serial communication module is a data transmission module with EDR Bluetooth protocol based on Bluetooth Specification V2.0. With the continuous development of Bluetooth technology, Bluetooth dual-mode modules have appeared, which can not only support classic Bluetooth, but also support low-power Bluetooth. What is the difference between the HC-05 classic Bluetooth module and the Bluetooth dual-mode module?

This time we use HYXKIOT's Bluetooth 5.0 dual-mode module HY-BT102 for comparison.

1. Bluetooth chip

HC-05 module adopts CSR BC417 chip, Bluetooth 2.0 version. The chip is powerful, stable, and supports SPP communication. However, due to the impact of the global new crown epidemic, the supply is unstable and the cost is rising.

HY-BT102 is a Bluetooth 5.0 dual-mode module, which can support SPP, GATT communication. Using Chinese chips, the cost is relatively low, and the supply is stable, meeting the needs of most consumer products.

2. Working mode

The HC-05 embedded Bluetooth serial communication module (hereinafter referred to as the module) has two working modes: command response working mode and automatic connection working mode. In the automatic connection working mode, the module can be divided into Master and Slave And loopback (Loopback) three job roles.

HY-BT102 Bluetooth 5.0 module support UART communication, support AT command Mode and Throughput Mode. It’s support Master slave mode, and auto-connect mode.

3. Data Transmission Speed

Bluetooth HC-05 module support SPP data transmission, the speed up to 50KB/S.

HY-BT102 Bluetooth 5.0 dual-mode module support SPP and BLE data transmission, SPP speeds up to 60KB/S, BLE speeds up to 40KB/S. The module data transmission speed is higher than the HC-05 module, for the Bluetooth thermal printer, POS printer, medical product, HY-BT102 is a nice choice.
