BLE-EZM031

Description

The module provides BLE transparent transmission function with high power RF output up to 8 dbm. It integrates Nuvoton M031BT , Power Filter and RF filter into a small size stamp-hole package with 11x11x1.4 mm dimension.For the BLE transparent transmission application, an external MCU can control it and do BLE transmission via an UART interface. The BLE module supports two operating modes: AT command mode and data transmission mode. In AT command mode, user can use AT command to control BLE module or get related information from BLE module. In data transmission mode, user can do bidirectional data transfer with another BLE central device such as mobile phone.
