The Bluetooth Slave UART Board provides bluetooth solution for adding wireless capability to your development system. It is suitable for applications where wireless bluetooth data transmission is needed. The Bluetooth Slave UART Board works in slave/device mode.
We provide both "Bluetooth Master UART Board (aka, the Master Module)" and "Bluetooth Slave UART Board (aka, the Slave Module)", each of them works in single mode only. It is impossible to switch working mode for the module. The white spot on the top indicates a Master Module.
For establishing communication, there're something should be noted:
The Master Module embeds the same AT command set with the Slave Module, expect one - the AT+NAME command, which is not embedded in the Master Module.
Both the Master Module and Slave Module are designed to use 3.3V power supply only. Be careful to use voltage translators (series connects a 1K resistor) on communication lines when connecting it to 5V systems.
