5. Detailed function
5.1 LDC reception
E330-400T13S module receives in LDC mode. The module is in the LDC (Low Duty Cycle) ultra-low power receiving mode
when powered on. The specific working mechanism is that the module periodically wakes up from sleep to detect the wireless
wake-up code. If there is a valid wake-up code, turn on RX Windows, otherwise, it will restart again after timeout. Go to sleep.
As shown below:
LDC cycle is software configurable
Sending mode. When the module sends data, it can automatically load the wake-up code corresponding to the LDC cycle.
Both sender and receiver need to configure the same LDC cycle.
5.2 Single point wakeup
The module has a single-point wake-up function, which can effectively suppress the problem of false wake-ups between devices
with the same frequency and different addresses; in the internal design, the module address will be configured as the SYNC address of
the hardware radio frequency chip, which is used to synchronize the receiving process and send The receiver chip will automatically
filter this data packet if it does not match the receiving synchronization word; the sender uses the short pr synchronization
word when sending the wake-up code;
