MIT app Inventor BLE permission problem with android

[Pieter_J_van_Horssen]

I found the solution to the BLE permission problem at a post from @ABG Since I am very new to the blocks concept, I wonder if it was possible to provide me with a copy of those (working example) blocks from ABG into my project. There are a number of blocks in Anke's post that I cannot find , like the blue "ïf" one in the top of the block. Can someone help me out here?

Rgrds,

Runtime Error need android permission on bluetooth scan permission

Canned reply from @ABG (thanks!). (Canned Response) These blocks can be dragged into your Blocks Editor to request permission(s) for Bluetooth scanning and connecting. All three parts are needed. [to apiLevel result] [when Screen1 .Initialize do] [when Screen1 .PermissionGranted permissionName do] Thanks to @Anke for the original code. My changes include use of the Screen1 permission blocks to avoid the possibility of a typo using a TinyDB tag particular to BT permissions and on…

Thanks for replying. I am using MIT APP Inventor block editor and it is not possible to drag and drop as you mentioned. So what is the secret to get this done?

@Pieter_J_van_Horssen

drag and drop

A way to group projects by theme

There is a recent addition to the Blocks Editor that lets you drag Downloaded Blocks Image files into the the Blocks Editor workspace. (The .png files hold hidden text.) This only works for individually downloaded images that have not been hand editted. Watch this little video for when the Blocks Workspace turns green as a .png file is dragged into it. [Drag and Drop Downloaded Blocks Images] P.S. Note how the cube_root_test image did not make it into the workspace, because I ruined its …

Thanks, i was able to get the blocks.

[Pieter_J_van_Horssen]

I get an error on TinyDB in the blocks........

Any idea?

[ABG]

No,

show us both the error and the blocks?

Try this one (build the APK and test it):
BluetoothClient_permissions.aia (7.0 KB)

Get the API Level of the device

This is an extension to get the API level of the device from the Android version that is currently running. de.bodymindpower.GetApiLevel.aix (4.8 KB) That's all: [grafik] Update (Dec. 30, 2021, ver 3): GetApiLevel_3.aix (5.0 KB) [grafik]

You are very new to AI2, so you missed one important point.

You have to drag into your project in the Designer from the components pallette, all the components whose blocks you will need.

I suggest taking the grand tour of the Designer component pallettes, and reading the names and functions of all the components.

Unfortunately dragging AI2 blocks does not carry along the components for those blocks.

Thanks very much for the advice ....

Can someone help me out here?

Did you try my test aia (post #9)? Does it (especially the APK) work for you?

[Pieter_J_van_Horssen]

I have been busy Otherwise so I will test it in the coming days. I will let you know .....

[Pieter_J_van_Horssen]

@Anke on advice from ABG i will first acqaint myself with everything like where do the components come from. Watch the tutoriaks etc....

[Anke]

@Pieter_J_van_Horssen

i will first acqaint myself with everything

I would test first if it works. And if so, then you can always research more deeply.

[Pieter_J_van_Horssen]

@Anke I tested your aia and it worked. It could find all blue tooth Including Mcqueen.
Great stuff, thanks.

[Pieter_J_van_Horssen]

@Anke can I somehow copy your BLE solution into my project? I have a project for moving my Mcqueen but need your Bluetooth aix in there to get it working.

[Anke]

@Pieter_J_van_Horssen

but need your Bluetooth aix in there to get it working

There is no Bluetooth(Client) extension.
You have my test aia and the relevant blocks. So where is the problem?

[Pieter_J_van_Horssen]

I was not clear in text. What i mend was how to import your bluetooth aix into mine project . I have a project to command the Mcqueen via Bluetooth but want to include your aix to do the connection business . I hope this is clearer...
