The protocol stack calls the emitter to enter the dead loop

[tuopu]

The protocol stack calls the function "otplatradioreceive". Since the radio is in the transmitting state, it returns ot_ ERROR_ INVALID_ State, enter the dead loop. Please ask about the logical sequence of calling the radio, and how to avoid calling the otplatradioreceive function in the transmitting state.

Calling otPlatRadioReceive is valid during tx and is expected to be handled by radio platform implementation.
The expected behavior is that platform must abort/stop the oging tx and enter rx mode. For example, this can be used if/when "ack timeout" is implemented by OT SubMac code.

Here are the valid radio transitions (from platform/radio.h):

/**
 * The following are valid radio state transitions:
 *
 *                                    (Radio ON)
 *  +----------+  Enable()  +-------+  Receive() +---------+   Transmit()  +----------+
 *  |          |----------->|       |----------->|         |-------------->|          |
 *  | Disabled |            | Sleep |            | Receive |               | Transmit |
 *  |          |<-----------|       |<-----------|         |<--------------|          |
 *  +----------+  Disable() +-------+   Sleep()  +---------+   Receive()   +----------+
 *                                    (Radio OFF)                 or
 *                                                        signal TransmitDone
 *
 * During the IEEE 802.15.4 data request command the transition Sleep->Receive->Transmit
 * can be shortened to direct transition from Sleep to Transmit if the platform supports
 * the OT_RADIO_CAPS_SLEEP_TO_TX capability.

thank you,After testing, it has indeed been realized. Thank you very much。
