How not to block during recording
The problem I have at the moment is that if a phone call comes in during my recording, even if I don't answer, my recording will be interrupted The phenomenon of recording interruption is that the picture is stuck, and the recording can be resumed automatically after the call is over. But it will cause the recorded video sound and painting out of sync Through the AVCaptureSessionWasInterrupted listening, I can get to record the types of alerts and interrupt As far as I can tell, a ringing or vibrating phone can block the audio channel. I found the same scenario in other apps, you can turn off the ring tone or vibration, but I don't know how to do it, I tried a lot of ways, but it doesn't work BlackmagicCam or ProMovie App, when a call comes in during recording, there will only be a notification menu, and there will be no ringtone or vibration, which solves the problem of recording interruption I don't know if this requires some configuration or application, please let me know if it does

How to make Bluetooth transfer rate faster
I used two iphones to transfer data via Bluetooth, and the MTU used 512 bytes.I got 56bps in withResponse mode and around 200bps in withoutResponse mode.I wonder how to achieve a faster rate.Let's say LE 1Mbps mode or LE 2Mbps mode.My central device and peripheral device are both iPhone, I don't know if there is a limit between them.My goal is just to know how can I achieve a faster rate 1、Two iphones connected to Bluetooth 2、Test separately with withoutResponse and withResponse 3、Calculate the transmission rate per second 4、In withoutResponse mode, the peripheral receives about 46 packets of 512 bytes per second 5、In withResponse mode, the peripheral receives about 13 packets of 512 bytes per second 6、So I get rates of 56bps and 200bps
