Command
pm [sleep_mode] [wake_source] [vote1] [vote2] [vote3] [param1] [param2] [param3]
Params
sleep_mode：sleep mode (parameter range: 0-3):
0:normal sleep;
1:low voltage;
2:deep sleep;3:none
wake_source：Wakeup Source (Parameter Range: 0-5)：
0：GPIO；
1：RTC；
2：WIFI/BT；
3：USB（BK72xx is not supported, other projects are supported);
4：touch；
5：none
Vote1: vote2: vote3: module id for the vote to move to sleep:
8:(BT)
9(WIFI)
12(APP)
param1：The meaning varies depending on the source of the awakenings:
GPIO：GPIO ID
RTC： Awake Time
WIFI/BT：
touch：channel ID of touch
param2：The meaning varies depending on the source of the awakenings:
GPIO：Awake method:
0：Low-power
1：High-power
2：Rising edge
3：Falling edge
RTC和touch：No param,default is 0
param3：BT sleep time;
this parameter is compatible with the interface for sending commands.
It is recommended to set the time to 1000000000 (100s), and the reason for setting such a large value is to use the time set by the internal module of the BT module as the standard.
Usage Scenario
Example 1: Using GPIO as a awaken source to wake up the deepsleep device:
1）After booting and starting for 5 seconds, (after the boot-up, BT, WIFI, and CPU perform initialization).
2）Input：
A. PM 2 0 8 9 12 9 0 1000000000 :Let the system enter deepsleep, use gpio for wake-up, 9 indicates the gpio ID, and 0 represents low-level wake-up.
B. If you want a certain GPIO to be woken up by a high level signal, connect it to a low level for its initial state before the test, and to a high level for waking up.
C. If you wish to wake up a GPIO from a low level, then connect the initial state of the GPIO to high before the test, and connect it to low when waking up.
D. If you want a specific GPIO to wake up on the rising edge, set the initial state of that GPIO to low before the test, and connect it to high voltage when it wakes up.
E. If you want a certain GPIO to wake up from a falling edge, do not set the initial state of that GPIO to high before the test; connect it to low when it wakes up.
