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 nRF24L01+ 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.
