This module is nPA+LNA,  the drive mode is exactly  equivalent to nRF24L01P,  the user can operate 
according to the nRF24L01P  manual  (Please see nRF24L01P  manual  for more details). 

 

As interrupt pin for IRQ,  it can be used to wake-up  MCU and achieve fast response;  

 

But the user can get the interrupt status through SPI (not recommended,  it is not conducive to the overall  powe r 
consumption, and with low  efficiency

 

CE  pin can be high level for long-term,  but it needs to set as POWER  DOWN  mode when the module write 
registers, and it is recommended  that CE  is controlled by MCU  pin. 

 

Make sure the CE  pin connect to LNA  enable pin , when CE  equal to 1, LNA  is turned on, when CE  to 0,  LNA  is 
turned off. This operation is perfectly matched with the transceiver mode of nRF24L01;  that is to say, users do not 
have to care about the LNA  operation 

 

If the automatic response is needed, the CE  pin must keep high level when transmitting, instead of keeping high  
level time  just more  than 10us like  the datasheet mentioned.The operation we recommended  is: when CE  equal to 1, 
the module begin sending, after sending all,  then make  the CE  equal to 0,  instead of making  the CE  equal to 0 a fter 
10  us.The reason is: the module turns into receiving mode immediately  after sending L01P,If  CE  equal to 0,it  means 
LNA  closed, will  not be beneficial  to the receiving senility
