TXEN
、
RXEN must be connected,among which RST control chip reset
，
TXEN, RXEN are for controlling RF
switch.

Make it ground well with large space for grounding and small power ripple. Filter capacitor is necessary and make
sure it is close to pin VCC and GND.

SPI communication rate should not be set too high, usually around 1Mbps.

In transmitting
，
set TXEN as high communication level
，
RXEN pin is low level; In receiving, set RXEN as high
communication level,TXEN is low level; Before powering off, set TXEN
、
RXEN as low level.

Re-initialize register configuration when the chip is idle for higher stability.
