EWM104-BT09 Series Product Overview

The EWM104-BT09 series is a Bluetooth to serial port slave module based on Bluetooth protocol version 5.0. It is small in size, low in power consumption, and works in the 2.4GHz frequency band. The module is developed based on Tailingwei's TLSR8208BER chip, and uses common AT commands to set parameters, which is simple and fast to operate. The module supports slave role, Bluetooth broadcast, data transparent transmission, and air configuration. It supports data transmission with a maximum baud rate of 1000000bps.

EWM104-BT09SP BLE Low Power

Compatible with Bluetooth BLE 5.0 protocol, supports IBeacon and ordinary broadcast switching and automatic broadcasting at startup. The module supports slave role. Supports multiple serial port baud rates, serial port transparent transmission, the maximum serial port baud rate supports 1000000 bps, and the maximum MTU is 200 bytes.

Use AT command configuration, and automatically recognize AT commands in wake-up mode. Support Bluetooth parameter air configuration function; support custom 16-bit and 128-bit UUID.

Supports transmission power modification, with a maximum transmission power of 11.5dBm. Under ideal conditions, the maximum distance can reach 200m (EWM104-BT09SX).

The ultra-low power sleep function can effectively reduce power consumption and save battery costs. The battery voltage detection service can grasp the power status of the device in real time.

This series of modules can be widely used in smart wearables, home automation, home security, personal health care, smart home appliances, accessories and remote controls, automobiles, lighting, industrial Internet, smart data acquisition, smart control and other fields.

Configure

The module supports two configuration methods: serial configuration and over-the-air configuration. These two configuration modes are basically the same, before the air configuration must be through the AT + AUTH = 123456 authentication password, i.e., to the remote configuration service UUID input 123456, the module is allowed to use the air configuration after the authentication is passed. The authentication period for over-the-air configuration is the current connection, and if the device is disconnected and reconnected, it needs to be re-authenticated.

After the module is in the wake-up state, it is in the configuration mode by default, and can be configured directly through the AT command.
