Hello! I ask for help in optimizing the decoder from ttn:
/*function Decoder(bytes, port) {
// Decode an uplink message from a buffer
// (array) of bytes to an object of fields.
var value=bytes[0]<<16 | bytes[1]<<8 | bytes[2];
if(bytes[0] & 0x80)
{
value |=0xFFFFFF000000;
}
var latitude=value/10000;//gps latitude,units: °
value=bytes[3]<<16 | bytes[4]<<8 | bytes[5];
if(bytes[3] & 0x80)
{
value |=0xFFFFFF000000;
}
var longitude=value/10000;//gps longitude,units: °
var alarm=(bytes[6] & 0x40)?“TRUE”:“FALSE”;//Alarm status
value=((bytes[6] & 0x3f) <<8) | bytes[7];
var batV=value/1000;//Battery,units:V
value=bytes[8]<<8 | bytes[9];
if(bytes[8] & 0x80)
{
value |=0xFFFF0000;
}
var roll=value/100;//roll,units: °
value=bytes[10]<<8 | bytes[11];
if(bytes[10] & 0x80)
{
value |=0xFFFF0000;
}
var pitch=value/100; //pitch,units: °
return {
Latitude: latitude,
Longitud: longitude,
Roll: roll,
Pitch:pitch,
BatV:batV,
ALARM_status:alarm,
};
}
