The first version of DBM01 module was released as the peripheral module DBM01-S with the baund rate is fixed. It was designed for LED lamp control so the function of it is simple and power-saving was not considered because the lamp is powered with AC electrity. A lot of customers commented the inadequacy of this version so our engineere adopted the valued suggestions and released the second version of DBM01. For the new verison:

1. central/peripheral mode can be selected in one module
2. Power-saving modes are introduced
3. Four types of pairing mechnisms are available for more applications

Please check the datasheet 2.0 of DBM01 carefully if it is what you need before procurement. For those customers who bought the first version of DBM01 module and would like to try new DBM01 modules, we can offer favorable discount for the same quantity you bought for the first version. Please contact us throug Tindie or email to nocorn1[@]gmail.com. We will send the discount code to you after comparing your contact details in our customer database.

Details

DBM01 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 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 can be used to communicate with other Bluetooth devices such as iPhone system. This module can be switched between Central mode and peripheral mode by external I/O pin or AT commands. In peripheral mode, users can set modules in different power-saving modes by changing the inquiry time through AT commands. DBM01 provides four types of matching modes for Central and Peripheral modules, which provides high flexibility for different applications.
