UART  baud  rate  can  be  different  between 

communication parties 

l

 

The  UART  baud  rate  has  nothing  to  do  with 

wireless  transmission  parameters  &  won’t 

affect the wireless transmit / receive features.   

 

 

 
----------------------------------------------------- 
 

l

 

The  lower  the  air  date  rate,  the  longer  the 

transmitting  distance,  better  anti-interference 

performance and longer transmitting time. 

l

 

The air date rate must keep the same for both 

communication parties.

The network with same number cannot exist in 
the same region.

Communication is not available for the devices 
with different network.

Only one master exists in the network.

network.

------------------------------------------------------- 

l

 

This bit is used to the module internal pull-up 

resistor. It also increases the level’s 

adaptability in case of open drain. But in some 

cases, it may need external pull-up resistor. 

 

-------------------------------------------------------- 

l

 

The wake-up time for master cannot be less 
than the monitor interval time of slave, 
otherwise, it may lead data loss. 

l

 

The longer the wake-up time, the lower the 
average receive current consumption. 

l

 

The same WOR time for master and slave is 
recommended when master needs to wake up 
slave.
