STM32F411 doesn't receive data about rf24 HOT 4 CLOSED

I connected an additional power supply to the STM32 board, and now it works!!!!
So, power from USB isn't enough for NRF24L01+PA+LNA.
@2bndy5 thank you so much!

    radio.begin();
    radio.setAutoAck(1);
    radio.setRetries(0, 15);
    radio.enableAckPayload();
    radio.setPayloadSize(32);

A few problems here:

1. radio.begin() doesn't need to be called twice.
2. Care should be taken when setting the auto-retry delay (0 means 250 microseconds). The delay specified here is the amount of time that the radio waits for auto-ACK packets. The datasheet recommends using 500 microseconds (1 means 250 + (250 * 1) = 500 ) or more when using ACK payloads (of at least 5 bytes).
3. Using ACK payloads requires enabling the dynamic payloads feature. Internally this is done for pipes 0 and 1 when enableAckPayload() is called, but just beware other pipes won't be usable unless the enableDynamicPayloads() is invoked.
4. Building off of point 3, setPayloadSize() (for statically sized payloads) is useless when using dynamic payloads feature.

I tried different configs, pin connections, examples from the lib, power supplier, SPI speed, etc. but can't fix it.

I highly suspect this is a power supply problem due to the use of PA/LNA modules. If you tried the library examples (specifically the ACK payloads example) and it still failed on your STM32, then I think this is a hardware problem (not a software problem). Did you read through our COMMON_ISSUES.md?

@2bndy5 Thank you for the quick answer.
Some bugs in the code can be as I modified it a lot of times during debugging.

Yes, I tried the ACK payloads example, here are the results:

As you can see in the screenshot, the payload on the STM32 isn't available.
And after switching a role, Arduino can't send data.

Did you read through our COMMON_ISSUES.md?

Yes, a few times)
But I haven't tried to use a capacitor before, because I use a power adapter like this:

So, will try to add a capacitor.

Just make sure the adapter board's VCC pin is getting at least a stable 150 mA (at 5 V of course).
