Hi, I have been working on an app for a school project and I need to connect my app to an Arduino board via Bluetooth. However, the BLE scan function returns “undefined” as an output no matter what I do. I am using Thunkable Live on an Android phone. I have also allowed all permissions and switched…

@rariac , can you add a location sensor to your project and try again please? Thanks

hi @rariac , try adding a list viewer and settimg text items of list viewer rather than a single label. looks like you are trying to set text of a label to a list of mac addresses and I’m not sure you can do it that way.

My project actually does have a location sensor in it. I’m sorry I didn’t mention it because I thought they were unrelated haha. What should I do now?

Hi! So I tried using a list viewer instead of a label and now there is not output at all not even the “undefined”. Also, just in case something else is interfering with it, the code for my entire page is below. [Screenshot 2020-07-30 at 5.01.45 PM] I actually got this code from another thunkable …

hi @rariac , I just duplicated these simple blocks and it works for me. Are you getting a mac list if you swap Device Names with Device Ids? I’m starting to wonder if you have a hardware issue. Can you install BLE scanner or a similar app and check for signals on that as well.

hi @eddie.rebehy ! I don’t know what a mac list is, but after switching the blocks around I’m still not getting any output. I can’t download anything at the moment but I will update you about the BLE scanner once I get wifi.

hi @rariac I’ll let you do your own research on this but In simple terms, mac address is a unique number that is used to identify the ble device. scanning for names may show blank lines if a device is advertising without a name but it will always have a mac address and hence you can see if a device…

So i was trying to do the same thing with the BLE component. These are the blocks that i am using [image] The error messages i get are as follows, BleError: BluetoothLE is powered off i turn on bluetooth BleError: Location Services are disabled i turn on gps The message stays put on the…

I have written my apk with MIT Inventor using “AddressesAndNames” scan and it works within 2 seconds delivering pairs of MAC & Name. Just works, as it should to. Thunkable was my first choice, but when I cannot scan names (MACs are scanned, names empty) - complete BLE function in Thunkable is usele…
