Data analysis example for JavaScript:
function decodeUplink(input) {
var obj = {};
var warnings = [];
obj.battery = (input.bytes[1]&0x1F);
obj.vol = (input.bytes[2]);
obj.temperature = (((input.bytes[4] & 0x80 ? input.bytes[4] – 0x100 :
input.bytes[4]) << 8)
- input.bytes[5]) / 10;
obj.humidity = input.bytes[7];
if (obj.temperature < -10) {
warnings.push(“it’s cold”);
}
return {
data: obj,
warnings: warnings
};
}
