Altertative method to configure parameters in node about enigmaiot HOT 1 CLOSED

You may upload configuration to SPIFFS using data upload on Arduino or Platformio.

File name is "config.json".

Format is like this:

{
  "networkName": "You_network",
  "networkKey": [  decimal number array with sha256 of key  ],
  "sleepTime": 10,
  "gateway": "Gateway mac address",
  "nodeName": "Your_node"
}

Plain network key is encoded as ASCII characters filled up to 32 characters with 0x00. For instance: if your key is 1234567890 hex equivalent is 3132333435363738393000000000000000000000000000000000000000000000

You may calculate sha256 using online converter as https://emn178.github.io/online-tools/sha256.html

Result hash is a53d6c160dc1358d307786f8c78b8446ec395da65ddd00e069bc81beb51c2f25

So networkKey field in file should be:

[ 165, 61, 108, 22, 13, 193, 53, 141, 48, 119, 134, 248, 199, 139, 132, 70, 236, 57, 93, 166, 93, 221, 0, 224, 105, 188, 129, 190, 181, 28, 47, 37 ]

It is not simple but is feasible. Sorry, it was not designed to be done so.

You may program a simple Python script to build your JSON file. If you do so please share it here so I can include it in repo.
