No Map Data in Access Point Mode

[noscript]

This fork claims to work cloud free, yet I cannot get the maps working without connecting to Internet.

How to Reproduce

1. Flash vacuum_valetudo_re_2008.pkg on a Gen2/S5 cleaner.
2. Connect to the cleaner's AP roborock-vacuum-s5_miapXXXX
3. Open http://192.168.8.1/ in browser
4. Start the cleaning
5. Go to Map view

Expected behavior
Map being updated in real time.

Actual behavior
Seeing "NO_MAP_DATA".

Vacuum Model: Gen2/S5

Valetudo Version: 0.9.2

You'll have to differentiate between "cloud free" and "unprovisioned mode".
If you do not connect the robot after flashing the firmware to a Wifi, it will stay in "unprovisioned mode". I've never tested the behaviour of the robot in this state yet, because everyone in reach of the signal could so easily connect to the robot, but it could be possible, that there are no map updates in this state. If you've connected it successfully to a Wifi (even a Wifi without internet connectivity) everything will work like expected! All connections to xiaomi cloud are blocked and the robot will run "cloud free".

Actually, device's firmware just doesn't send any map data when the robot is in AP mode, since it thinks there's no reason to try doing that when it's not connected to the internet, as obviously it doesn't know that with valetudo we're working locally.

Probably this can be changed with binary patching some manufacturer's services running on the robot, but generally trying using the device in AP mode is a bad idea from the security point of view, and also the device would shut down the AP after a while anyway, it won't be up forever.

My bad. Connecting to a WiFi without internet connectivity actually makes the maps working.

Is there a workaround to use maps in AP mode?

Why would it be the case if I set a password to for AP?

I think that could be changed to keep it permanently on.

Then the only thing you need is to learn how to patch ARM executables, find the condition where it checks whether it's in AP mode, and disable it to make the maps uploaded regardless of Wifi mode. Unfortunately I have literally zero experience in this.

Btw it will require no changes from valetudo - only a patch of, most likely, /opt/rockrobo/cleaner/bin/AppProxy.
