Announcing SDK 6.0 for Fitbit Versa 3 and Sense

[JonFitbit]

SDK 6.0 has just been released. Checkout the developer blog for more info:

How do you access the resources folder files in SDK 4.3?

It no longer seems to work.

Which mean Clocks and Apps development and support for anything other than Versa 3 and Sense may have ended.

[Gondwana]

Did you update the import for fs?

[Guy_]

New format

import * as fs from "fs"

doesn't work in 4.3, it used to in 4.2 and 5.0

Also the file structure is now inaccessible, in 4.3, 5.0 and 6.0 in the OS Simulator 0.9.1

[JonFitbit]

SDK 4.3 does not require the import changes, that only applies to SDK 6.0. 4.3 has the old version of Rollup pinned, so the existing code should just work.

[Guy_]

Hi Jon

Was using fine before in 4.2 & 5.0

import * as fs from "fs"

Now it won't work.

fs.readFileSync() complains about needing a function

[TypeError: Expected a function]

[JonFitbit]

SDK 6 needs to the new imports. 4.3 needs the old import syntax.

[Guy_]

Yes, but what was working before now isn't.

Previously  in 4.2 & 5.0 with

import * as fs from "fs"

fs.readFileSync() was working

Changing to 4.3 it no longer works.

Worse if you change the 4.2 import [which shouldn't be necessary as it was working fine before 6.0] to

import fs from "fs"

then

fs.readFileSync() no longer finds the files.

with the OS Simulator 0.9.1

There shouldn't be a need to change the working 4.2 code and if you do [going back to older versions] its not working.

In 5.0 its not working, nor in 6.0 either, as the files aren't found.

So 2 problems.

[Guy_]

One problem solved:

It turns out the file not found message was incomplete but it is still necessary to change the working 4.2 import to the older version for it to run in 4.3.

[JonFitbit]

You only need to update to 4.3 if you want the Weather API.

5.0, 4.3, and 4.2 use the old style imports.

6.0 uses the new style imports.

[Guy_]

What do you call old style import for FS ?

Have always been using till now

import * as fs from "fs"

This doesn't work anymore. So a code change is required.

[JonFitbit]

The code change is required for SDK 6.0 only.

[Guy_]

No, a code change is required for 4.3 .

Previously 4.2 ( like 5.0 ) supported

import * as fs from "fs"

As in documentation

But 4.3 won't.

4.3 will only support the older version

import fs from "fs"

Hi Jon,

So, if our existing clock face doesn’t need the weather api or the weekly azm goal info, will it be necessary to upgrade the build to sdk 6.0? Or the clock faces will continue to function normally if built using sdk 5.0 for Versa 3 and sense?

[Krish_2009]

Maybe update the docs saying that old syntax for 4.3.0

[Guy_]

@JonFitbitCan having to revert to

import fs from "fs"

cause increased memory usage and Fatal Jerryscript Error: ERR_OUT_OF_MEMORY??

[Guy_]

@JonFitbit  Hi Jon

There definitely seems to be a bug with 4.3.0, the built code seems to be far more full of carriage returns and the built I/O commands contain errors, unless the source is changed [which causes larger commands], and even removing a considerable portion of the original source it still will not fit in memory.

The original 4.2.0 built code loads fine still.

Does this mean that development for the OS 4 pre Versa 2 platform has already inadvertently ended for anything but tiny mickey mouse projects? Or will there be a fix so development can continue?

[Acrux]

New weather options seems like it may have some issues, the weatherCondition is only returning a number.. so far even using the example made for github does the same.

import * as cbor from "cbor";
import { me as companion } from "companion";
import { outbox } from "file-transfer";
import weather from "weather";
import { dataFile, wakeTime } from "../common/constants";

if (companion.permissions.granted("access_location")) {
   weather
     .getWeatherData()
     .then((data) => {
       if (data.locations.length > 0) {
         const temp = Math.floor(data.locations[0].currentWeather.temperature);
         const cond = data.locations[0].currentWeather.weatherCondition;
         const loc = data.locations[0].name;
         const unit = data.temperatureUnit;
         console.log(`It's ${temp}\u00B0 ${unit} and ${cond} in ${loc}`);
       }
     })
     .catch((ex) => {
       console.error(ex);
     });
}

Returns - [11:28:55 AM]It's 25° celsius and 6 in Sparta

Still no access to o2 😑

@JonFitbit  Hi Jon, any news when we will get the 4.3 rollup problem fixed?

[Guy_]

Hi Jon, Its now 3 weeks there has been a problem with 4.3, will it get resolved soon?
