Installation Instructions

Product Introduction

BTM0305 is a BLE module with a master-slave feature. The module is based on nRF52832 with an

ARM Cortex-M4F processor from Nordic Semiconductor. Therefore, the BTM0305 features

Bluetooth 5.0, high performance and ultra-low power(ULP).

The user's MCU is connected to the module through a serial port (UART), so that it enables

bidirectional communication of data with the mobile device. After receiving the data from the

serial port of the user MCU, the module will automatically send it to the m bile device; The

mobile device can write data to the module by the APP, and then the module sends the data it

received to the user's MCU through the serial port.

Module features (such as serial port baud rate, broadcast interval, etc.) support both local and air

configuration modes. Various parameters of the module can be configured by “AT Command”,and

parts of the “AT Command” can be stored in flash to ensure the configuration dose not lost when

the module is power-off.

With the mentioned feature, users may spend less time and cost to developing products by using

BTM0305.Development become easier.

Feature

 Support Bluetooth 5.0 protocol, high-speed transmission.

 Support a wide range of supply voltage from 1.8V to 3.6V.
