Using the library in a project

Call decodeBLEJson(JsonObject) with the input being of the Arduino JSON JsonObject type. If the device is known the JsonObject will have the decoded device data added to it.

Example

Input JsonObject:

{
  "servicedata": "712098000163b6658d7cc40d0410024001"
}

JsonObject after decoding:

{
  "servicedata": "712098000163b6658d7cc40d0410024001"
  "brand":"Xiaomi",
  "model":"miflora",
  "model_id":"HHCCJCY01HHCC",
  "tempc":32,
  "tempf":89.6
}

TIP

If you are using ArduinoJson library with your project (like TheengsDecoder) you may have to align the ArduinoJson build options into TheengDecoder with it. To do so, go to decoder.h (opens new window) and align the flags with your project. In particular you may have to remove ARDUINOJSON_USE_LONG_LONG=1.

Encrypted data

Decoders for encrypted data, indicated by the "encr": true tag, will send a JsonObject with the properties cipher, counter, message integrity check and MAC address, e.g.

{
  "encr": true,
  "cipher":"62511158bd25",
  "ctr":"b8f09364",
  "mic":"5b573115",
  "mac":"AA:BB:CC:DD:EE:FF"
}

With a correct bindkey this encrypted data can be decrypted and sent back to Decoder for properties decoding.
