Any fix for makeImageRequest on CIQ 4+ devices?

On devices with CIQ4 or greater, the Graphics Pool is involved.  Are you doing anything due to that?

The callback method for makeImageRequest is never called, or else I would see the first statement of that function which is a println telling me that. This error is (apparently) from makeImageRequest itself.

How big is the image?  Remember with makeImageRequest, it's actually been converted to a format usable on the watch using a Garmin Server.  Could it be related to AMOLED vs MIPS as with AMOLED, you're probably getting a larger image.

The 955 is CIQ5 but is MIP and has a smaller display (smaller image?).  What happens with it?  Same as the f7x? The 255s is also CIQ5 and has a smaller display than the 955.

I'm trying this with a Fenix 7x which is only slightly bigger than the 955. I have even tried it with a 3x3 9 pixel image, which according to nginx requires 517 bytes for the return headers and png image. The graphics pool usage according to the sim memory dialog is 89712 out of ? It doesn't look like a memory space issue. On the Captain Marvel the 3x3 bitmap resource requires 817 bytes. Maybe it's a graphics pool thing because in theory makeImageRequest is supposed to return a bitmap reference in CIQ 4+, but it seems less like low memory and more like something else.

Since you asked, it does not work on the 955 or the even smaller Fenix 7s.

I'm not, the callback function is never called, the error comes from makeImageRequest so there is no response and no data. If there was data it would be saved in an application storage variable, and background.exit(data) would be a dictionary {"image"=>"cPic") which is the name of the storage variable. This works in CIQ 3.

	public function onReceiveCenterImage(response as Number, data as imgData) as Void {
		logTime("response " + response + ", getTimer " + System.getTimer());
	

Line 2 never gets executed in CIQ 4+.

Yes, I forgot you mentioned you got the error before the callback.

What does your makeImageRequest look like, as far as parameters, etc. ?

Have you tried this on a real device or just the sim?

Just the sim. I'm trying to get this working before I go through the developer hoops and get my beta watch face approved. But your point is well taken, it may just be a sim problem, but it's still a problem.

Beta apps are never approved.  As soon as you upload one, you can use it right away.  If there are no app-settings, just try a sideload..

I modified to always try to get an image instead of on demand. Here's the CIQ_LOG.BAK from the watch itself:

Have you tried getting a different image from someplace else?
