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 power
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 after
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
