The BLE remote control we sell (which communicates with the iPhone via Bluetooth and emits an infrared signal) can no longer be paired with iOS13.
Pairing was possible on iOS12.
This remote control does not support L2CAP.
Is it possible to pair a device that does not support L2CAP with iOS13?
Please give me some hints.
I solved this problem.
I found that [Manufacturer Name String] must be encrypted...
Is there any document about this?
