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
};
}
