FAQ & Troubleshooting?

A list of reminders

  1. Not connecting? Make sure you have followed Lilgo installation instructions
  2. Not connecting? Don't forget to use the serial chip (I did this so many times)
  3. Not connecting in apple home? The range of the wifi to the Lilygo can affect performance
  4. Not connecting in apple home? I found a laptop quicker to find devices than a phone for testing reliability
