Simulator enforces lower JSON size limit than real devices in SDK 9.1

It seems that SDK 9.1 introduced changes to how the simulator handles JSON size limits. The release notes state:

“Enforce max JSON response size limit for BLE web request.”

However, it now appears that the limits enforced by the simulator are lower than those on real devices.

I have attached an example JSON. It works correctly on my Epix Pro Gen 2 using a sideloaded app compiled with SDK 9.1. In the simulator, the same JSON now results in a -402 error.

  • This is listed as a bug fix.  It makes sense you see it in the SDK first as it could be some time before the fix rolls out to the firmware for all the devices and this way you can test/verify your apps before it hits users on real devices

  • I just checked but could not find anything in simulator.json that defines this limit.

    My guess is that it is a global limit, independent of the device.

    It is also worth noting that a limit was enforced before as well. In the past, I was already able to trigger -402 errors in the simulator, just with much larger JSON responses.

  • If the simulator knows (or should know) the limit, then it is somewhere in the simulator.json? That would be an interesting piece of information. I hope they'll also add the limit for web requests!
