Set state example

Closed this issue 8 years ago · 9 comments

All the examples I've found are about how to get data or read a tag's state, but I can't figure out how to change a tag's state. Specifically, I'm trying to reset a tag's state from 'Movement Detected' to 'Timed Out'. Is this even possbile?

I don't think you can do this programmatically. Unless what you mean is to reset the Moved state immediately rather than waiting for the timeout to reset it. The iOS app (and I assume the Android app too) does give you that option, so I suppose there must be an API method to do it. I'll look into what that could be next week. If you know that and in which screen you can do this now the web application can you share that here. (There are a number of API methods that are otherwise undocumented but are used by the web app code, so one can infer from that how to call it.)

Yes, you can do that from the app, and it's actually documented in the API: ResetTag

And here is the JavaScript method used by the web app

function resetit(btn, wid) {
	var tag = taglist_cache[wid];
	var oldhtml = show_finding(btn);
	$.ajax({
		url: WSROOT + "ethClient.asmx/ResetTag",
		data: "{id: '" + tag.slaveId + "'}",
		headers: allTagManager ? { 'X-Set-Mac': tag.mac } : null,
		success: function (retval, textStatus) {
			restore_finding(btn, oldhtml);
			updateTag(retval.d);
		},
		error: function (xhr, textStatus, exception) {
			popup_error(xhr, btn, null, exception.message);
			restore_finding(btn, oldhtml);
		}
	});
}

We can disregard the btn variable, all we need is the id of the tag.

I see. Perfect. I'll add that next week.

Pull request is up. @ahmadtawakol which release series are you using? I think I can back port this to 0.6.x, but am not sure about earlier than that. (The pull request is for the 0.7.0-beta pre-release, which is not on npm yet.)

Answer 5 · 2017-03-26T03:23:22.000Z

Thank you! This is perfect. I'm not running wirelesstags-js yet, so I'm not on any release. Can I install it directly from git? Or does it have to be on npm?

Answer 6 · 2017-03-26T16:32:29.000Z

Absolutely, you can install from git. I suppose this means I don't need to bother with backporting, it'll just become a new feature of the 0.7.x series.

(Your only risk in installing directly from Git is that if you install from master, a later update may jump you to a new minor or even major version than the one you were on, which may change some of the API's signatures or behavior. You can prevent this by installing from a commit (if you use npm). If installing from the npm repository, npm allows you to say which version is eligible for being upgraded to.)

I tried installing from git yesterday, but I kept getting lots of errors which were all full of "nan", even the directory names and the files were all called "nan". I don't have my laptop with me right now, so I'll try again tonight and send you the full errors

Ok, never mind my last post. Turns out that I needed to install gcc 4.8 and set it as the default gcc, I was on 4.6.

I installed this package from the commit you made. I tested it out and already implemented in my project, and it works perfectly, this is exactly what I needed. Thank you again for adding this.

Glad it works for you! Post an issue if something doesn't seem to work as advertised.
