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 broadcasting time through AT commands.
DBM01 provides four types of matching modes for
Central and Peripheral modules, which provides high
flexibility for different applications.
