I need a tutorial on how to process data on android via wifi. F.e., I need to send some message to PC and receive some other message. How should I establish the connection? What should I do to be able to transfer data and how?
Sorry for the dummy question, but I can't find good manual. I'll be grateful for as detailed manual as possible, or for ome simple example on etablishing wifi connection and sending/receiving simple mesages.

You can use your phone's mobile data to connect another phone, tablet, or computer to the internet. Sharing a connection this way is called tethering or using a hotspot. Some phones can share Wi-Fi connection by tethering. Most Android phones can share mobile data by Wi-Fi, Bluetooth, or USB.
Restart your device. Open your Settings app and tap Network & internet or Connections. Depending on your device, these options may be different. Turn Wi-Fi off and mobile data on, and check if there's a difference. If not, turn mobile data off and Wi-Fi on and check again.
If your guest has an Android phone, head to Settings, Connections (or Network and Internet), then Wi-Fi on their phone. Scroll down to find where it says Add Network; next to it, you'll see a QR code icon. Tap on it and they can now quickly scan the code. Scanning the code should automatically connect the device.
