When does a watch decide to generate a PRF file?

Is there a way to make this happen when I want, or do I just have to hope the profile fairy pays a visit some night? This seems to be way more helpful than the simulator, but you have to keep the .debug.xml file that matches the .prg file if you update often during the development and testing process. There are many functions listed as <API Code> and <Native Code> so I can see how long they take and how many times they are called but I don't know what they are. These show up in the simulator so maybe there is a way to splice the XML files? Again, the profiler in SDK 4.2 is SO broken compared to 4.1. At least then the numbers were kinda close. They're just not going to fix it, it seems.

Apparently having the -k option set causes a PRF file to be generated. This works on a Fenix 7, but not on a Forerunner 235. Why is that? Is profiling on Forerunners just not allowed?

The 235 is a pretty old device with CIQ 1 and profiling on a device likely requires code in the vm (in the firmware). I'm sure it works on newer FR devices.

I'm not sure what the cutoff is, but it could be that only something like System 5 devices or greater allow on device profiling.

What's the conversion from CIQ version to System version?

Here's the System 5 announcement along with devices at that time.

When the profiler was announced...

Other devices were System 5 but are now System 6

"With more coming" means just what's on that page? Is there a page that says what's included in what firmware version? The simulator for the Forerunner 235 is 7.60, CIQ 1.4.4, but the actual watch is 8.20, CIQ 1.4.5. Not much difference in the CIQ versions (and why is the simulator behind?) but the major version difference in firmware seems like it could be significant.

"with more coming soon" generally mean newer devices, such as the 255 and 955 in the case of System 5 but now they are System 6. In the System 6 announcement "more coming soon" now included the 265 and 965.

For the 235, that's CIQ 1 and I've never seen a "System x" for it, but it's probably "System 1". Understand the 235 is ~7 years old right now. I can't recall the last time I even heard from a user with a 235, though I have a bunch of apps that support it

FWIW I used your hiking app more than a few times on it. I don't know how many are are still in the wild. I only upgraded because the glass cracked, otherwise I'd probably still be wearing it. It doesn't hold a charge like it used to, but it's still good for a week at a time. I'm still keeping it around because right or wrong I figure if my watchface works on it then it should work on just about all of them.

On the 235, that's Hike1. Starting with CIQ2 it's Hike2+. I can't recall the last time anyone contacted me about Hike1
