doubt with Computed Attributes

Greetings, I have some gps at20 it uses h02 port similar to sinotrack, but it has an additional cable to use in hood doors, trunk or extras, I understand that I must place a commputed attribute to that value but the truth is I have carried out several tests and I am lost, Can someone advise me, I attach the values that the GPS gives me

thank you

What are these parameters? It doesn't look like it's from Traccar.

its the translated protocoll, i flespi to see it give a minute i post the parameters as it comes directly from the gps

I'm assuming you want to extract some bits from the status. It should be possible with computed attributes. What we would would need to help you is the protocol documentation describing the bitmask and list of the values you want to extract. Make sure that your parameters are available in the doc.

these are the lines in original, as soon i get the documentation ill pot it here, it works great on 5013 the only thing that not works is that aditional cable

Even based on the samples you can probably figure out which bits are used for what in the status.

I have a week trying everything I can think of and no good results, I admit that this is surpassing me

What have you tried exactly? I think if you provide full details on your investigation so far, we can try to point you in the right direction.

formulas and combinations of true / false based on the state that I see in detail of the equipment and that (it seems) coincide with the information that the gps line gives me when changing the cable, but it has given me arid errors, I know that for the expert eye must be nonsense,

Before trying to create any computed attributes you have to figure out which bit represents what in the status field. Have you done that? If not, that's what you need to do first. Take your samples, take the status value, convert it into binary and check the difference. Once you have that information, post it here and we can try to help with the expression to use. Of course if you're still interested.

you mean here? vehicle.state : "FFFFBAFF? or here vehicle.state.bitmask : 4294949887 o in the original line

Yes.

in the three parts or in the one that is shown in the traccar details that would be vehicle.state.bitmask: 4294949887

Those are the same. Value FFFFBBFF (hexadecimal) is 4294949887 (decimal).

would this be then?
