MCU SIM ERROR?! (GL-E750 Mudi)

Hi,
When I “logread” my Mudi router, I can see A LOT OF error “MCU SIM ERROR” in very rapid succession. Pasting just a small portion of the log below so you get the idea how rapid is happening. Does anyone have any idea what that is?
Firmware: 3.217 Snapshot build (date: 2023/05/05)

p.s. it’s currently on the Repeater mode, there is no active sim card inside.

This is a normal phenomenon and will be improved in version 4.0 to match the on-screen sim card display

So it doesn’t negatively impact the battery usage?

yes.it’s just to check for a SIM card
