BC660 Light Sleep Mode

Technical Subjects

Can you please provide me a sample at commands to enter only Light Sleep Mode?
In that case is there a URC to notify the CPU?

Thanks

When the module’s modem enters the DRX/idle state, the module’s cpu can enter the Light sleep (some tasks enter the suspended state).But without any URC output, it is just a low-power mode of the mode

Hello and thanks for your answer
Can you also inform me about the necessary at commands that I must send to the module in orer to enter this mode?

Do I only have to send AT+QSCLK?

Can you also tell me the difference about the following URC’s
“ENTER PSM” and “ENTER DEEPSLEEP”. The Enter deepsleep is obvious but what about “ENTER PSM”? Can we say that the module is in light sleep mode when I get the “ENTER PSM” and don’t get the “ENTER DEEP SLEEP”?

PSM belongs to a network state. deepsleep requires that after the module enters PSM, the APP of the module is suspended and enters the sleep state
After camp on the network, the module needs to enter PSM first, and then enter Deepsleep; You can also enter Deepsleep mode via AT+CFUN=0
AT+QSCLK=1 is only used to enable the module to enter the deepsleep state, not immediately
