 2. You will need to "pair" the device by entering a PIN shown on the device screen. This can alternatively be done in the phone Bluetooth settings. If the Device has no screen, but it's connected via USB, it may be displayed on a serial terminal (921600 Baud). For a development device, the PlatformIO terminal would come in handy. Some nodes have buttons allowing you to change the page displayed on the nodes screen. If you double click this button, it will set the pairing code to `123456`.
 3. Edit the "Your name", e.g. to be "Mike Bird". This is the name that other people will see, so make it unique within your group.
 4. The initials e.g. "MB" should also be unique and will be used to identify you in the message history and on the device screens.

 ### Setup a channel
 
-To use Meshtastic, you need to setup a Channel and share the details with your group. The group is private and only those who have the details can join the group and see the messages. You will need to do this once initially, and then only when you want to change or make a new mesh network group. For a new device you will see there is a default setting, shown as `#LongSlow-1, Very long range (but slow)`. It is OK to use this initially.

+#### Device sleep period (This feature is disabled by default and no longer recommended)
 
 ESP32 devices can enter sleep mode to save battery life. During sleep Bluetooth is turned off. This setting allows the length of the sleep mode to be changed from the default 300 seconds (5 minutes). After this time period, they awake to check the phone for any queued messages and then go back to sleep, alternating between sleep and awake states. Receiving a message over LoRa (the LoRa receiver never switches off) or pressing a program button (if there is one on the device) also awakes the device.
