[BUG] Not able to send Telemetry using BLE connector

[vjvivek1983]

I am using a Thingsboard installation on EC2 machine as a server and I have a Raspberry PI 5 as the gateway. I am trying to fetch telemetry from a NRF node via BLE which sends the readings through advertisement message only. For that I have created a BLE connector on TB with the following configuration:
{
"passiveScanMode": false,
"devices": [
{
"name": "TEST",
"deviceType": "BLE",
"MACAddress": "FA:96:BD:45:08:XX",
"pollPeriod": 5000,
"connector_type": "ble",
"type": "hex",
"showMap": false,
"timeout": 10000,
"connectRetry": 5,
"connectRetryInSeconds": 0,
"waitAfterConnectRetries": 10,
"telemetry": [
{
"key": "temperature",
"dataSourceType": "advertisement",
"valueExpression": "[0:1]"
},
{
"key": "humidity",
"dataSourceType": "advertisement",
"valueExpression": "[0:2]"
}
],
"attributes": []
}
],
"logLevel": "DEBUG",
"name": "Rpi_BLE",
"enableRemoteLogging": true,
"id": "ed894e3c-2a34-4581-b959-25568e426157"
}

I do not see the device created on Thingsboard at all. Hence no telemetry also. While checking the logs I see the following:
