Is it possible to read from (and write to) a local file? (Fenix 3)

Former Member over 10 years ago

I want to write a personal workout check list. All exercises should be user configurable in a flat file that I just upload to the watch. An alternative would be getting the data with a http request - but I don't want to develop an additional smartphone app just to do that.

Is this possible?

Not possible. CIQ stuff can not read/write local files. Object Stores is as close at it comes.

Object store is part of the binary and can not be changed after compiling, right? That would mean recompiling every time the data changes :-(

I guess I need to write an android app to provide dynamic data to the Fenix3 app??!

No. The object store is a mapping between key/value pairs that are persisted. i.e.,

var list_of_names = [];

function addName(name) {
    // allocate space for additional name
    var new_names = new [ list_of_names.size() + 1 ];

    // copy all of the existing names
    var i;
    for (i = 0; i < list_of_names.size(); ++i) {
        new_names= list_of_names;
    }

    // append the new name
    new_names= name;

    // take over new array
    list_of_names = new_names;
}

function onStart() {
    var names = self.getProperty("Names");
    if (names != null) {
        list_of_names = names;
    }
}

function onStop() {
    self.setProperty("Names", list_of_names);
}
[/code]

Hmmm. But this solution would require to generate all data on the watch itself? That does not sound user friendly.

In the meantime I was looking into makeJsonRequest. I don't know anything about json but it sounds like a solution: I generate a config file, put it on a web server and load it via makeJsonRequest.
This should solve my problem. Now I just need to understand how to load a flat file using makeJsonRequest, parsing it shouldn't be a problem :-)

Long term, garmin is working on a general way to change this stuff so programs can be configured. Also, someone here wrote a program for the mac or pc to allow simple edits.

Thank you! You wouldn't know where to find that program? The search function did not help me a lot :-)
