	61	+The **Add data converter** window will appear.
	62	+
	63	+Let's create an uplink data converter for the device named '**Device A**'. Name it ‘**MQTT Uplink Converter - Device A**’ and select the Type as **Uplink**.
	64	+
	65	+Click on the **TBEL** button if it has not been selected by default.
	66	+
	67	+Modify the default TBEL function to match with your device as described below:
	68	+
	69	+* Uncomment** line 11**:
	70	+
	71	+//var data = decodeToJson(payload)//
	72	+
	73	+* **Line 13**: Assign your device name to the **deviceName** field. - We used **Device A** as it is to match with our device, **Device A **in the Devices section.
	74	+* From **line 38**: Modify the telemetry section to allow parsed data to be assigned to the fields.
	75	+
	76	+//telemetry: {
	77	+ temperature: data.temperature,
	78	+ humidity: data.humidity,
	79	+ rawData: payloadStr
	80	+ }//
	81	+
	82	+The modified uplink decoder function to match with **Device A** is shown below.
	83	+
	84	+{{code language="nono"}}
	85	+// Decode an uplink message from a buffer
	86	+// payload - array of bytes
	87	+// metadata - key/value object
	88	+
	89	+/** Decoder **/
	90	+
	91	+// decode payload to string
	92	+var payloadStr = decodeToString(payload);
	93	+
	94	+// decode payload to JSON
	95	+var data = decodeToJson(payload);
	96	+
	97	+var deviceName = 'Device A';
	98	+var deviceType = 'thermostat';
	99	+var customerName = 'Customer C';
	100	+var groupName = 'thermostat devices';
	101	+var manufacturer = 'Example corporation';
	102	+// use assetName and assetType instead of deviceName and deviceType
	103	+// to automatically create assets instead of devices.
	104	+// var assetName = 'Asset A';
	105	+// var assetType = 'building';
	106	+
	107	+// Result object with device/asset attributes/telemetry data
	108	+var result = {
	109	+// Use deviceName and deviceType or assetName and assetType, but not both.
	110	+  deviceName: deviceName,
	111	+   deviceType: deviceType,
	112	+// assetName: assetName,
	113	+// assetType: assetType,
	114	+// customerName: customerName,
	115	+  groupName: groupName,
	116	+   attributes: {
	117	+       model: 'Model A',
	118	+       serialNumber: 'SN111',
	119	+       integrationName: metadata['integrationName'],
	120	+       manufacturer: manufacturer
	121	+   },
	122	+   telemetry: {
	123	+       temperature: data.temperature,
	124	+       humidity: data.humidity,
	125	+       rawData: payloadStr
	126	+   }
	127	+};
	128	+
	129	+/** Helper functions 'decodeToString' and 'decodeToJson' are already built-in **/
	130	+
	131	+return result;
	132	+{{/code}}
	133	+
59	59	Once you modify the decoder function, click on the **Add** button.
