Is this a deliberate action from the Apple side ?
Why would it not let connect an SPP device ?

I have exactly same problem, did you possibly find a fix ?
Why does the BT SPP present itself as audio-card ?
This is the way tablets and laptops see it.

Here is what I see with the Linux bluetoothctl: Class: 0x2c0414 Icon: audio-card Paired: yes Trusted: no Blocked: no Connected: no LegacyPairing: no UUID: Serial Port (00001101-0000-1000-8000-00805f9b34fb) RSSI: -54 the problem is the "audio-card" - this way laptops and tablets see this BT device. C...

OK, I am working with ESP-IDF and I actually got to the stage where I can see and pair the BT of my ESP32 in classic BT mode. But, it refuses to connect, which I suspect is because the ESP32 is seen as audio-card and not a serial port. Is there a way to resolve this situation ? Are there any paramet...

Hello, I need the SPP mode too and actually I am not able to make it to work at all. With some older ESP-IDF I was able to get to a point where the BT was reported as audio device thus could not connect it as serial port with the newer ESP-IDF it is still reported as audio but is mostly dead thus no...

Thank you, thus from the programmer point of view the RTOS runs as if there was a single core as long as all the resources are properly protected by the semaphores ?

Is given task run always by the same core or it can be switched between cores ?

No, but I am writing to the console UART, which is already setup and open, correct ?

I am communicating with the GPS UART and it all works fine, I set it up, etc.
But the console UART is already setup by the system I understand.

What happens when a file is not properly closed: say the device happens to crash or be repowered ? Is some part of the file readable or is it all gone ? Is it possible to check if a given file is still being written or if it is already closed ? As one can guess I need these features for data logging...

In my application, I have enabled running the FreeRTOS on both cores and then I observed like memory overwrites, at least on the console output. My application would as well become unstable: it would run for an hour or two and then simply stop, not even restarted. Is there anything to consider when ...

If my application creates or needs files in the /spiffs is there an established protocol to exchange files through the console ?
Somethink like kermit or zmodem so one can easily transfer files over the serial conenction ?
