Hello everyone,
I want to build the tag location, to use for GPS.
I have 2 values sent from the device, lat and lng.
How do I combine them to make the location tag?
Thank you
const payload\_raw = payload.find(x =\> x.variable === ‘payload\_raw’ || x.variable === ‘payload’ || x.variable === ‘data’);
if (payload\_raw) {
try {
```
// Convert the data from Hex to Javascript Buffer.
const buffer = Buffer.from(payload\_raw.value, 'hex');
const data = \[
{ variable: 'Timestamp', value: Date(buffer.readUInt32BE(3)).toLocaleString() },
{ variable: 'latitude', value: buffer.readInt32BE(7) / 1000000 },
{ variable: 'longitude', value: buffer.readInt32BE(11) / 1000000 },
{ variable: 'speed', value: buffer.readInt8(15), unit: 'mph' },
{ variable: 'Angle', value: buffer.readInt16BE(16) , unit: 'C' },
{ variable: 'Altitude', value: buffer.readUInt16BE(18) },
{ variable: 'Electricity', value: buffer.readInt8(22), unit: '%' },
{ variable: 'Altitude', value: buffer.readUInt16BE(18) },
\];
// This will concat the content sent by your device with the content generated in this payload parser.
// It also adds the field "serie" and "time" to it, copying from your sensor data.
payload = payload.concat(data.map(x => ({ ...x, serie: payload\_raw.serie, time: payload\_raw.time })));
```
} catch (e) {
```
// Print the error to the Live Inspector.
console.error(e);
// Return the variable parse\_error for debugging.
payload = \[{ variable: 'parse\_error', value: e.message }\];
```
}
console.log(device)
}

Hi Roberto,
A location variable must contain an object called ‘location’ with lat and lng inside, e.g:
{
```
variable: 'location',
value: '26.199906, -80.141655',
location: {
lat: 26.199906,
lng: \-80.141655
```
}
}
I updated your parser:
```auto
const payload_raw = payload.find(x => x.variable === 'payload_raw' || x.variable === 'payload' || x.variable === 'data');if (payload_raw) { try { // Convert the data from Hex to Javascript Buffer. const buffer = Buffer.from(payload_raw.value, 'hex');const lng = buffer.readInt32BE(11) / 1000000; const lat = buffer.readInt32BE(7) / 1000000; const data = [{ variable: 'Timestamp', value: Date(buffer.readUInt32BE(3)).toLocaleString() }, { variable: 'location', value: `${lat}, ${lng}`, location: { lat, lng } }, { variable: 'speed', value: buffer.readInt8(15), unit: 'mph' }, { variable: 'Angle', value: buffer.readInt16BE(16) , unit: 'C' }, { variable: 'Altitude', value: buffer.readUInt16BE(18) }, { variable: 'Electricity', value: buffer.readInt8(22), unit: '%' }, { variable: 'Altitude', value: buffer.readUInt16BE(18) },]; // This will concat the content sent by your device with the content generated in this payload parser. // It also adds the field "serie" and "time" to it, copying from your sensor data. payload = payload.concat(data.map(x => ({ ...x, serie: payload_raw.serie, time: payload_raw.time }))); } catch (e) { // Print the error to the Live Inspector. console.error(e); // Return the variable parse_error for debugging. payload = [{ variable: 'parse_error', value: e.message }]; } console.log(device)}
```
