Store complete nodes and gateway connection data in flash ?

[quangvankts]

Hi gmag11
Thanks for the great library with very detailed documentation. I have few questions:

• How do I hardcode network name and network key for both nodes and gateway so I don't have to configure them individually after flashing?
• How do I save complete nodes and gateway current data into flash (including shared key, valid status etc) so they can load it up, skip registration and exchange data straightaway after a cold boot (I know it only takes 200ms to register but I want to experiment how fast nodes can work)
• DEBUG seems only work on my ESP8266 node but not ESP32 gateway. I tried "#define DEBUG_LEVEL VERBOSE" and "#define DEBUG_ESP_PORT Serial" at the main sketch with no effect. Serial.printf() still works as normal. (Im using Platform IO latest core)
  Thanks

Hello, These are three questions. I'll separate them into multiple issues and will close this. You can check #12, #13 and #14
