Bluetooth BLE UART Serial Pass-through Module


Bluetooth BLE UART Pass-through Module

The DM-U08 is Central and Peripherals 2-in-one Bluetooth UART Serial pass-through module. It is also called transparent Bluetooth module. Users can change roles (Central and Peripheral mode) and serial baud rate and device name via AT command. Parameters such as name and password are flexible to use. Once it is paired to a central/master Bluetooth device such as PC, smart phones or tablet, its operation becomes transparent to the users.
