DBM01-S is a type of low energy data transmission Bluetooth module based on CC2540 from Texas Instruments. Combining the advantages of compact size, extra low power consumption, strong anti-interference and long communication distance, it is very suitable for short range wireless communication in Things of Internet. The module integrates PCB antenna on board. Because the RF circuits of DBM01-S are well matched and optimized, users are free from time-consuming RF design and only need to focus on the slight work on UART communication.

DBM01-S is a slave module and can be used to communicate with other Bluetooth devices running Android or iPhone system directly without address matching mechanism. In these cases the Android/Iphone device act as the concentrator and collect data from each Bluetooth device with DBM01-S module. However DBM01-S is a type of peripheral device so communication can't be realized between two DBM01-S modules. DORJI will release central module in the near future, which the DBM01-C central module can communicate with DBM01-S slave device for transparent data transmission. The module keeps nearly all of the features of cc2540 so users can use as it a hardware platform only and overlap the codes to customize their own applications.
