We are developing an IoT device and face issues with automatic connectivity to the smartphone via Bluetooth, as we have to use a PWA instead of a native app. We consider using a standard profile (e.g. Headset Profile (HSP), Human Interface Device Profile (HID)) to enable communication via Bluetooth between device and PWA.
We now require a workaround for the following issue:
When using HSP/HID, existing connections to the smartphone's hardware (e.g. headset, keyboard) can be interrupted.
Have you faced similar issues and do you know workarounds for this?
Are you knowledgeable about alternative connection mechanisms (e.g. NFC, SIM) to connect IoT with PWA incl. pros and cons?
