CC1312R: continuous transmission

user3718583

Part Number: CC1312R
CODEC IC data to send audio with CC1312R Packetized data is transmitted, but since the microphone is an analog type and the antenna is nearby, packet noise is generated due to the wraparound of the RF signal. Since it is difficult to change the hardware, as a solution If packet data can be sent continuously without intermittent radio waves, We can resolve this issue. But I don't know how to do that. Can you tell me Since there is a mode to send random data continuously with test radio waves, Is there a way to put voice packet data instead of the random data?

    Hi,

    This is the description of the TX_TEST command. 

    The payload is only provided once and repeated infinitely. This command cannot be used to transmit data continuously.

    Regards,

    Thank you for your comment.

    Regarding TX_TEST command, 　I used it when I took the technical conformity test.

    I'm sorry that my explanation is insufficient for what I want to know. 　
    I will give a supplementary explanation.

    I am making a small device that wirelessly transmits the sound picked up by a microphone. A combination of CC1312R and a CODEC IC that digitizes analog audio.
    When audio is converted into data and transmitted in packets, it looks like as follws:

    __------____-----------_____--___　　FSK transmission as follow picture


    Waveform intermittent radio waves.
    Normally, there is no problem with this, but due to the miniaturization, the microphone line circuit and the antenna are close to each other, and the noise synchronized with packet transmission is generated in the circuit due to radio wave interference. "Since the device is already complete,
    It cannot be changed easily.

    f software can solve the problem,
    If it is possible to avoid intermittent radio waves, there will be no change in electric field strength.
    The noise should be reduced. Not only changes in the strength of radio waves
    The change in current consumption linked to the ON/OFF of radio waves may also be the cause of noise. In any case, I would like to transmit continuously like TX_TEST in order to reduce the change, but when the packet has been sent, the transmission radio wave
    It will stop. "Even if you change the data transmission method,
    The interval can only be narrowed down to as follws:

    -----------_----------------------_-------------------

    , and when the radio wave is momentarily turned off, noise occurs.
    If there is a way to send data but not stop radio waves, please let me know.
    Of course, it is necessary to send normal microphone data, not for testing.
