I'm following the instructions to connect via router, but nothing seems to happen when I press the button on the robot. It doesn't seem like it's even trying to scan the QR code. Connecting directly works fine.
Am I missing something obvious?

Has the robot asked for the QR code? It will ask when ready.

It has not asked, but never seems to. Is there something I need to do besides hit the button and wait? And is it just a short-press of the button? If I hold the button long enough it says something like "WiFi Reset." Besides that it seems to just sit there.

It took 2 times for mine to ask. It was a little slow also but just try waiting and keep trying. Naturally , make sure you didnt type your router password wrong. It's easy to do.

Is the switch on the robot in the right position? It's not on phone direct mode?

Launch the RoboMaster app on your phone and click Connect and then select Connect via Router.  After you enter your Router WiFi password, it will generate a QR code and you can scan that using the RoboMaster camera.
If that doesn't work, turn off the RoboMaster and stop & start the RoboMaster app.

Yes, the switch is in the right position. (Always good to check the obvious though!   )

I've been careful with the router pwd, but even if I had it wrong, I would expect it to get to the point of asking for the QR code.

I've restarted everything several times and it still doesn't seem to work.

I'm beginning to wonder if there is something odd in my router setup. I'll dig into that this evening if I can't get it to work otherwise by then.

You get it working?

Nope. I'm having a couple of other issues too that are making me think either I've got a bad control unit, or the SW on it is borked (I am up to date with firmware).

When connected directly via Wi-Fi, I can control the robot manually, but the follow person feature never finds a person in the frame no matter the lighting conditions, distance etc.

Also, custom programs never execute. Even the most basic tutorial won't run when I hit the run button in the debugger.

I contacted DJI customer support. We'll see what happens.

Ouch good luck. Customer service is usually less than helpful. I'd just send it back and get a new one.

I was getting a message that I was not connected to my router but I was. Worked fine on another Android phone so I figured it was because I'm using iOS13 beta.

The latest firmware update (v00.05.0026 released 7.16.2019) seems to have resolved my issues.

(Note that prior to this, I *was* up-to-date with firmware, so either my previous firmware install went awry, or some change in the new firmware fixed things. In any case, all's well now.)

I was so hoping this thread will solve my problem too, but unfortunately even FW v00.05.0028 doesn't work for me.
I tried with 2 different routers in two different networks and two different hosts (android and windows).
Password is checked and the wifi switch is set on the robot.
Every time when robot camera sees the QR the robot turns red and turns it's "head" as to show "no".

i have the same issue, is there a way to have him ask for a password or reset if it took an wrong QR code?
nevermind i found it that little red button could be pushed too...   

I'm also having a problem like this. Today I updated my phone to android 11 and now when I'm trying to connect via router it only tells to go connect but I'm already connected ... WiFi direct stil works but without the router option battles ar of the menu any ideas ???

Off I use a tablet with a older android version everything runs smoothly

Hello, as far as I understand, in order to connect to the router I have to wait for the robot to ask for my QR CODE?

Are you changing the switch from AP to Router mode in the robot? If it is correctly set, when you press the connection button the robot will say "Scan the QR code from the app".
