Sleep mode
- Edited
Was there a solution to this issue?
I have been using a Wifi Hotspot in the car, but the Wifi in the Dudu7 would not always connect to it so have just installed my SIM card directly to the unit. The data works much better now, but today the system booted from scratch rather than from sleep after being left for approx 5 hours. It had never done this before I installed the SIM card.
As an update to this, I have now switched back to using a WiFi Hotspot rather than have a SIM card connected directly to my DUDU7. Since then it had always woken from sleep perfectly.
Judging by what others have mentioned in this thread and my experience it seems there is a bug that causes the system to randomly fully restart, rather than just wake from sleep, when a SIM card is installed.

What is the date of your MCU version? If possible, please try upgrading the MCU firmware.
MCU firmware version starts with 2024.01.24.
Presuming that is a date, that seems quite old considering I only updated the system 2 weeks ago to remove the Voice Assistant.
If one isn't included in a general update, how do I know if an MCU update is available/required and if it is how do I do it? Is this going to lose all my app settings again like the last update did?
By getting a DUDU7 with the DUDUOS an integral, pre-installed OS, I really don't feel the user should need to know all this stuff about MCU versions etc. If an update is required for parts of the system, it should tell you and updating it certainly shouldn't lose any existing settings.
User_mdhjrybs mcu updates are quite risky to perform and normally they should not be updated. As duduOS is not really a full OS but rather skin and additional software for FYT platform, it cannot update MCU. MCU is like a BIOS firmware for your PC and you don't have BIOS updates almost never with any operating system updates.
I'm on MCU original release and have no problems so far with it, so I don't update (you may brick your device if something goes wrong).
So its perfectly understandable that MCU updates are not included and they're not offered routinely.

That's good to know, thanks. I wonder why @DUDU-Meng advised me to do it then?!
I don't intent to update anything, unless absolutely necessary, after my last experience of it.
I've mostly found workarounds for the bugs I've found and it seems to be working OK with my hotspot rather than 4G, so I plan to run it as it is for now.
User_mdhjrybs because for some reason FYT fixed something in the last mcu firmware and appears that by accident they also fixed SIM connection after sleep.
