Cubecell BMP180

#1

Hi
I use cubecell with sensor BMP180 , connected to TTN gateway, TTN and to Tagoio.
Payload is string : 0000c0418096c5475f9b56410002
I dont have any payload parser or decoder to get out temperature data etc.
Any help please.

Here ya go

function tofloat32(a1,a2,a3,a4){
                            var s=(a1&0xff)>>7;
                            var E=(a1<<1&0xff)|a2>>7;
                            var M0=(a2&0x7f)<<16|a3<<8|a4;
                            var M=1;
                            for(var i=0;i<23;i++)
                            {
                              if(M0>>i&0x01==1)
                                {
                                  M=M+Math.pow(2,i-23);
                                }
                            }
                            var result=Math.pow(-1,s)*M*Math.pow(2,E-127);
                            return result;
                            }

function Decoder(bytes, Port)
{
var temperature = tofloat32(bytes[3],bytes[2],bytes[1],bytes[0]);
var humidity = tofloat32(bytes[7],bytes[6],bytes[5],bytes[4]);
var voltge = bytes[8]<<8|bytes[9];
var result={
“sensor”:{
“Temperature”:temperature,
“Humidity”:humidity,
“Voltge”:voltge,
}
}
return result;
}

Hi, thanks a lot. I am not sure where to put this function? I have tried in tagoio parser but nothing happens. Definitely i am doing something wrong. This is my first parser integration so, apologize for bothering.

Sorry, know nothing about Tagoio. I use this parser in TTN and it works.fine. Sorry 'bout the poor formatting, couldn’t remember how to insert code. Think I should have used */

Good luck
