Does the project use extensions? Typically this error indicates that a component couldn't be initialized and on iOS the main culprit is when a project includes extensions (extensions are not supported on iOS due to App Store policy). If you want to PM me the project we can take a look and do a deep dive to understand what's happening.
I'm new to the MIT app inventor, and I have been using an iPhone to try to connect my phone to a BLE and it gives me the same error. In my case (using an iPhone), how can I establish a connection between the app and the BLE device without using the BLE extension?
BLE isn't supported in the iOS version at this time. We're still discussing the best course of action on this, but my guess is that we will probably move the BLE extension into the core App Inventor components in order to support BLE on both platforms without the need for an extension.
Hey, Anything new with this? We are an Arduino based high school program and until we can use app inventor on iOS devices to control BLE devices (HM-10 etc.) we can't incorporate this amazing app.
We have over 2,000 students in the program and this would be a great addition!
