Issue while getting data from multiple BLE beacons (working in advertisement mode) to Thingsboard platform using Thingsboard Gateway stack.

[Garv-Bhatia]

I am using BLE beacons to send temperature and humidity values to thingsboard platform using thingsboard gateway stack.
I am using this beacons in advertising mode.

Note: Please update BLE connector configuration documentation for advertisement mode also.

So, It is working fine when I am using this setup just for one ble beacon. But as I am adding configuration for second beacon also, I am getting values first time working fine but after that I don't know what is happening latest telemertry values are not updating for my devices, it is not working fine. It seems to be getting stuck somewhere, as there is also a lag in the logs as I can see on the platform.

This is my ble connector configuration file for 2 ble devices:

  "name": "ble Connector",
  "passiveScanMode": true,
  "devices": [
    {
      "name": "BLE Device 1",
      "deviceType": "BLE",
      "MACAddress": "##:##:##:##:##:##",
      "pollPeriod": 10000,
      "connector_type": "ble",
      "type": "hex",
      "telemetry": [
        {
          "key": "temperature",
          "dataSourceType": "advertisement",
          "valueExpression": "[10:12]"
        },
        {
          "key": "humidity",
          "dataSourceType": "advertisement",
          "valueExpression": "[12:14]"
        }
      ],
      "attributes": [],
      "attributeUpdates": [],
      "serverSideRpc": []
    },
    {
      "name": "BLE Device 2",
      "deviceType": "BLE",
      "MACAddress": "##:##:##:##:##:##",
      "pollPeriod": 10000,
      "connector_type": "ble",
      "type": "hex",
      "telemetry": [
        {
          "key": "temperature",
          "dataSourceType": "advertisement",
          "valueExpression": "[10:12]"
        },
        {
          "key": "humidity",
          "dataSourceType": "advertisement",
          "valueExpression": "[12:14]"
        }
      ],
      "attributes": [],
      "attributeUpdates": [],
      "serverSideRpc": []
    }
  ]
}

Please check if I am using correct configuration or any change is required, It is working fine if I am using for only one device that is by removing the part of BLE Device 2 from this configuration.

Versions

Again requesting please update connector configuration documentation for advertisement mode also.
