BLEGattCentral

Bridge BLE GATT services and characteristics read and write to IoT DAP protocol.

  • leverages BLE GATT (Generic Attribute Profile) standard
  • services and characteristics can be configuring setting gattProfileConfig property
    • Advertised device name List of devices name to be discovered (names the manufacture uses to advertise the device)
    • Frequency to read characteristics value(s) an ISO 8601 string duration; representing how frequently characterictics values will be collected; defaults to 1 minute iso 8601 PT1M
    • The amount of read cycles, the smoothing logic will consider for calculating lost observations
    • Service UUID and name

    • Characteristics UUID and name(can be selected for a list of supported characteristics specified at GATT services
