CE can be connected to high level for a long time, but the module must first be set to POWER DOWN power-down
mode when writing the register. It is recommended that CE be controlled by the single-chip pin;
The CE pin is connected to the LNA enable pin. When CE=1, the LNA is turned on, and when CE=0, the LNA is
turned off. This operation is a transceiver mode of nRF24L01;
If the user needs to answer automatically, the CE pin must maintain a high level during the transmission process,
instead of the high-level time mentioned in the n manual greater than 10us. The correct operation is:
CE=1 triggers the transmission. After knowing that the transmission is completed, it will set CE=0, instead of CE=0
after 10us. The reason is: after L01+ transmission, it will immediately switch to the receiving mode. If CE= 0, the
LNA has been turned off, which is not conducive to receiving sensitivity.
