The 802.15.4 protocol contains four basic sleep behaviors which can be divided into two categories: pin-controlled sleep modes and cyclic sleep modes. By default, sleep mode is disabled (SM = 0) so the radio will always be awake.
To wake up a computer via WOL, you should enable WOL in BIOS settings and configure network card. To enable WOL in BIOS settings, Switch on the computer and press ESC, F1, F2, F8 or F10 during the initial startup. Depending on the BIOS manufacturer, a menu would appear. Go to the 'Power' tab and enable 'Wake Up On LAN'.
Directly to 1.8-V, 2.5-V, 3.3-V, or 5-V logic IOs. The transceiver has a low-power standby mode which supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN1044-Q1 transceiver also includes many protection and diagnostic features including thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply under. The next time you wake up at 3 a.m. (or whatever time), give yourself 15 to 20 minutes to doze back into dreamland. If you’re awake longer than that, it’s best to get out. Remote Wake-Up refers to remotely turning on a networked computer by sending a network message (called a magic packet) that contains the MAC address of the computer. On receipt, the computer initiates the system wake-up. The computer receiving the magic packet does not need to be left “on,” as was the case before Remote Wake-Up became.
Tip Once you enable sleep mode, XCTU may display a warning message if you try to communicate with the module while it is sleeping (for example, to change the value of a setting). Press the reset button to wake it up.
Pin-controlled sleep mode
The Pin Hibernate (SM = 1) mode is controlled by the Sleep_RQ pin. In this mode, the XBee module will sleep when the Sleep_RQ (pin 9) is asserted or pulled high by connecting it to 3.3 volts. For the typical power-down current and wake-up times, see the legacy XBee/XBee-PRO 802.15.4 RF Module User Guide or the XBee/XBee-PRO S2C 802.15.4 RF Module User Guide.
Cyclic sleep modes
XBees have the ability to sleep and wake on a fixed schedule. This is the most common method of conserving power when a radio is being used as a simple sensor node. Within the cyclic sleep category, XBees offer two modes:
- Cyclic Sleep Remote (SM = 4) mode allows modules to periodically check for RF data.
- Cyclic Sleep Remote with Pin Wake-up (SM = 5) is the same as Cyclic Sleep Remote but with the option of also waking the module using physical pin 9.
In these two modes, you must configure the Time Before Sleep (ST) and Cyclic Sleep Period (SP) settings (described below). For the typical power-down current and wake-up times, see the legacy XBee/XBee-PRO 802.15.4 RF Module User Guide or the XBee/XBee-PRO S2C 802.15.4 RF Module User Guide.
Time before sleep (ST)
Defines the period of inactivity of the module (during which no data is sent or received) before returning to cyclic sleep. If the XBee is transmitting or receiving a message, it will not go to sleep. This setting is only applicable if the sleep mode is 4 or 5.
Cyclic sleep period (SP)
Defines the length of time an XBee remains asleep. This setting is only applicable if the sleep mode is 4 or 5.
For bidirectional communication with sleep modes, other protocols such as Zigbee or DigiMesh may provide more appropriate functionality.
Sleep-related pins
The XBee modules have two special pins related to the sleep mode: pin 9 and pin 13.
The Sleep control or sleep request pin, physical pin 9 on the XBee, is used in pin-controlled sleep modes to put the module to sleep when it is asserted or pulled high by connecting it to 3.3 volts.

The On/Sleep pin, physical pin 13, goes high when the module is awake and low when it is sleeping. Generally, this pin is connected to an LED as a visual indication of the module’s current sleep state or to a microcontroller input to wake up the control unit and/or provide a simple way for the control unit to know if the radio is awake or sleeping.
Congratulations! You have just completed the section, so you are ready to do the Example: enable sleep mode.

Benefits of Waking Up PC Remotely?
Well, there are so many benefits of switching to wake up option.
- Your PC gets enough time to reboot when sleep mode is active. This improves PC performance
- Power saving, useful for the environment
- Better performance of hardware
- Not require any physical presence of anyone all the time
TIP: Generally, it has been noticed that keeping your PC in sleep mode if you have a little span of rest reboot your PC and improves startup speed and normal running speed of your system. Suppose you have done your work for 4 hours regular and you need a 1-hour break then it is recommended to make your PC to Sleep mode except doing Shut Down. This optimizes your PC performance.

Now let us check what are different ways to Turn ON your PC remotely.
How to Wake PC Remotely from Sleep Mode?
1.Using WoL (Wake on LAN) Option
This option is bit easy to wake your PC remotely. If you are unfamiliar with the term WoL then firstly know what it then proceeds further.
WoL (Wake on LAN) is a protocol medium or follows a particular standard that wakes your PC using Network message. All you need is to set a programme on another device connected to the same Local Area Network.If you are unable to connect the devices with the same LAN then you need to check out a different method.

With these steps you can control your PC in easy way. Now let us check some other ways for this.
2. Using a Static IP on your PC
In order to remotely wake your PC, you must provide your PC a static IP address. There are many ways to know your current IP address which we are going to check in this.
Providing a Static IP is another best way to awakening your PC. As your router may allow your device different IP address periodically. But once you have set to the static IP then the further configuration would be easy.
Follow some simple steps to allocate static IP on your computer. Firstly check your Physical address, IPv4 address.
- Open Control Panel. Navigate to Network and Internet> View Network Status and Task.
- From the left pane menu list, select Change Adapter Settings.
- From the list of all your connected networks, right click on the network you are using currently. Click on Status.
- On a General tab of your LAN, tap on Details.
- Here you can see all your current Physical address of PC, IPv4 address. Take a screenshot of this.
- Now again go back to Change Adapter Settings screen, this time on your LAN network, right-click to open Properties section.
- Scroll the list and look for Internet Protocol Version 4 (TCP/IPv4). Select it and then click Properties.
- Under General tab, your settings are set to be default automatic obtaining of IP address. Mark Use the following IP address and Use the following DNS server address respectively.
- Enter your IP address, Subnet mask, Default gateway, Preferred and Alternate DNS server and click OK.
It has noticed many times that after switching to static IP or manually changing an IP Address and DNS server address, internet not working properly. At that time check the quick guide to fix this problem.
Now again you can remotely wake your PC using TeamViewer application.
