found nothing, I'm depressed
I found this in a 2020 post MIT App Inventor cannot connect to mBot. Android App Force Quit when search for devices - mBot - Makeblock Forum . I do not use Mbot so I have no idea whether it will help you or not. This seems to be a link you already tried.
Why? Do something else as the project when you reach a dead end.
This is one of my students' Robot contest.
- Speed test with line follower
- Customization of Mbot2
- Creation of a smartphone application to control the mbot2 and play a Robot football match against a robot.
Suggest your student might need to use the Makeblock free software rather than App Inventor/ It might be his/her only alternative Here is a link https://www.makeblock.com/pages/software.
Otherwise you might ask about an App Inventor extension on the Makeblock discussion forum. mbot2 robot football - Google Search
Last year the Appinventor applications created by my students had no problem connecting to the Mbot.
In my new establishment, I have two Mbot1 to which I have just put the blutooth chips.
Unable to connect to mbot.
I have this message:
"connot connect to blutooth connect"
Is the Bluetooth mbot chip paired with your Android?
See Makeblock Bluetooth Dongle Operation Guide | Makeblock Education . It discuses pairing. or use MakeBlocks instead of App Inventor.
What Android version are you using. This discussion suggests the .the 2.0.4.aix extension on the mbot site does not work with Android 11+ .
This discussion might be useful Sending data to mBot via Bluetooth - mBot - Makeblock Forum See where one user used this MIT App Inventor Code on the Android:
BTArduinoClient2Devices_ahu.zip (3.1 KB) and he says You will need to pair the mBot with the Android device using the Bluetooth settings 1st, then connect within the app.
I forgot to specify that the connection is made from my android phone.
The connection was working fine last year....
Please note it is Mbot + Bluthoot card
Last year I managed to connect Mbot1 with Appinventor applications.
But there, impossible....
I thought it was from the card but the provider told me no.
It tells me about connection problem because of android 12...
I took an old tablet with an old android and it does not work better....
You can see, the message I have on my phone...
Put aia project here.
Thanks I didn't see your reply sorry
you have to ask for permissions, see also
Thank you, I try tomorrow with the students.
I add this routine like that, in addition to the initial program?
And in case it still does not work, drag a bluetooth client component into the working area without using it to get the required permissions in the manifest
mBot.aia (235.6 KB)
Then follow the next tip.
I don't understand the next tip.....sorry
Add a built-in bluetooth component to your project.
I added the:
But I still don't see the Mbot whether with an old or new Android
I forgot something??
Do you see the mbot in the list of paired or unpaired devices in android bluetooth settings?
Or can you see the mbot with a regular bluetooth component?
When you added the bluetoothClient component, are you still getting this error?
