We have developed a live iOS application, built using Swift and UIKit, that enables users to connect via Bluetooth to an EV charging box. Once connected, users can start and stop the charging process directly from the app.
The app also requires an active internet connection initially, as it uses server-side functionality to select and authorize the charging box. However, we recently discovered an issue affecting users on iPhone 14 and iPhone 15 models, specifically when the device enters Satellite mode (Emergency SOS via Satellite) — i.e., when there is no mobile data or Wi-Fi.
In this mode, the system Satellite screen is triggered and Bluetooth stops functioning, preventing our app from connecting to the EV box. Users are unable to proceed, even though the app would still be usable via Bluetooth once the box is selected.
We have already declared required Bluetooth background modes (bluetooth-central, bluetooth-peripheral) in Info.plist, and the app functions perfectly outside of this scenario. However, the behavior in Satellite mode appears to either disable Bluetooth entirely or restrict access from third-party apps.
We’d like to know
- Is this the expected default behavior on iOS in Satellite mode?
- Is there any entitlement or exception available to allow Bluetooth access in such emergency scenarios (especially for critical utilities like EV charging)?
- Can an app like ours be made visible under the Satellite settings, or request access under this mode?
This is a concern for users in remote or basement locations where mobile data is unavailable, and they rely solely on Bluetooth to charge their vehicles.
Please advise if there is a workaround or planned support in future iOS versions.
Thank you.
