Bluetooth Serial Port settings for Windows10 PC
It is true that with Windows own Bluetooth software two virtual COM ports are created after pairing:

when connecting your terminal program to the first you are actually instructing Windows to attempt to establish the Bluetooth connection to the remote paired device, and if the connection is established the RFCOMM channel will be opened for the exchange of data
when connecting your terminal program to the second you are actually instructing Windows to load the SPP SDP record and to remain waiting for incoming connections from the remote paired device.

difference between incomming BT com-port and outgoing?

An incoming port is used when a remote device established a connection to your device, and is exposed as the SerialPort service to the remote device.
An outgoing port is used to make a connection to the serial port service on a remote device (e.g. GPS Receiver).

ESP32 Developer – Priority
Arduino ESP32 FreeRTOS 2: How to use Task Parameter – Task Priorities – Task Handle – Idle Task Hook

There are 3 types of scheduling: Co-operative Scheduling and Prioritized Pre-emptive Scheduling with time slicing and without time slicing.

Prioritized Pre-emptive Scheduling with time slicing:
task with higher priority will pre-empt the tasks that have lower priority. And tasks that have the same priority will run in turn every time tick interrupt occurs (RTOS has a timer interrupt to measure the time, every time the interrupt occurs RTOS will check that it is time to unblock or wake a task).
Prioritized Pre-emptive Scheduling without time slicing:
task with higher priority will pre-empt the tasks that have lower priority. And tasks that have the same priority will not run in turn every time tick interrupt occurs (the task that is running, will continue running until it is pre-empted by high priority task).
Co-operative Scheduling:
context switch occur when running task change from Running state to Blocked state or call taskYIELD(). The next running task is the task that has highest priority and is in Running state.

– If the priority 11 task is pinned to core 0 or has no core affinity, the priority 11 task will preempt on core 0.
– If the priority 11 task is pinned to core 1, core 1 will not preempt.

> 3. A high priority task that never calls vTaskDelay will eat

If the high priority task is pinned to a core, then it will starve the lower priority tasks on that core from cpu time. However if the high priority task as no core affinity, it can be possible that the task will bounce between the two cores, giving the lower priority task on each core a chance to run. However, writing a task function that never blocks is very poor application design. We guard against cpu starvation using the task watchdog timer.
