Features
l
Star network:
It supports a maximum of 31 slaves to send data to master at the same time. Eight groups with 31 slaves of network
can run simultaneously in the same area.
l
Handshake:
The handshake between the master and the slave will make the whole communication more reliable. Once one of the
transceivers starts a communication and the communication is being interfered, the transmitter will retransmit the data for a
maximum of three times. The users can receive the transmitting results.
l
Ultra-low power consumption:
WOR (wake on radio)，is especially suitable for battery powered applications. When module
works at slave-receiver mode (mode 2), the module’s maximum receiving response time is 2000ms, and the average current is
below 30uA.
l
FEC:
Forward Error Correction has high coding efficiency & good correction performance. In case of sudden interference, it can
correct the interfered data packets proactively, so that the reliability & transmission range are improved correspondingly. Without
FEC, those data packets can only be dropped.
l
Encryption Algorithm:
The module has the function of data encryption & compression. The data transmitted features
randomness. With such function, data interception becomes pointless. Data compression can decrease the transmission time &
probability of being interfered, while improving the reliability & transmission efficiency.
l
Watchdog:
With a built-in watchdog, the module runs precise layout and time. Once an exception occurs, the module will restart
in 0.107 second, and continue to work according to the previous parameters.
l
Sleep
mode:
When the module works in sleep mode (Mode 3), it is available for configuration, but not for transmitting & receiving.
The typical current is 2uA in this mode. It can still receive the configuration from the MCU.
