Bluetooth Module HM-10 (Bluetooth V4.0 Module)

Bluetooth Module HM-10 (Bluetooth V4.0 Module)
The HM-10 is a versatile Bluetooth 4.0 Low Energy (BLE) module designed by JNHuaMao Technology to provide a comprehensive wireless solution. It integrates data transmission, remote control, and PIO state acquisition functionalities into a single, compact unit. Based on the TI CC2540/1 chipset, the module is engineered for flexibility, allowing developers to implement robust Bluetooth connectivity without needing an external microcontroller for basic operations.

A key characteristic of the HM-10 is its ability to operate in both master and slave roles, enabling it to initiate connections to other devices or accept incoming connections. The module’s behavior is highly customizable through an extensive set of simple text-based AT commands, which can be sent via its UART interface to modify parameters like the device name, baud rate, and operating mode. This programmability makes it adaptable to a wide range of project requirements and scenarios.

The module supports three distinct work modes: a transparent transmission mode for bidirectional data exchange, a remote control mode for managing the output states of its I/O pins, and a PIO acquisition mode for monitoring sensor or switch inputs. It also features intelligent power management, including a sleep mode that can be woken via a specific data string or a system key, ensuring efficient operation in battery-powered applications.
