Smart RF Studio Questions

I am using Smart RF Studio and would like to know two things.  1) In the Packet TX mode, what is the default time for the packet interval ?   2) In the Packet RX mode, is there a way to save the received data that appears in the window to a file so that it can be viewed ?  The "Dump Data to File" button does not appear to perform this function.

    Hi Dave

    1) If you check the advanced box in the Packet TX tab you can set the packet interval manually or use the default value given by SmarRF Studio

    2) To save the received data to a file (txt) you need to firat open a txt file to dump the data to. This can be done by pressing the button on the left of the "Dump data file:" window (see screenshot below). Choose a file name and press open in the dialog box that appears. Now all received data will be dumped to that file as soon as the radio has finished RX.

    Hi Martin,

    Is there a way to process or parse the packets in Real-Time ? Such as the data can be read while the receiver still hasn't finished RX ... Is it possible...?

    Regards,

    Prudhvi

    Hi Prudhvi

    Yes, you can always read out received bytes from the RXFIFO while the radio is still receiving data. Just be aware not to read out more data than is actually in the RXFIFO at the time. Else you will go into a FIFO_ERROR state caused by FIFO_UNDERFLOW.

    This method is used if you for instance have packets longer than the RXFIFO size, and you need to read out data so the FIFO does not get overflowed.

    Hi Martin ,

    Thanks for your reply. My question is can it be done through smartrf studio.

    In smartRF studio can we read data from file while it is dumping data into file.

    Can you also please say how  can we read out received bytes using RXFIFO ?

    Hi

    SmartRF Studio will read out while receiving when the packet is larger than the FIFO size, however this is handled by the firmware and is out the users control.

    If you are referring to the data dump txt file mentioned earlier in the post, this will not help you. The data will be written to the file post receiving the data.

    I'm not sure I understand the question. What chip are you referring to? For all our transceivers, in normal mode, all received data is placed in the RXFIFO. To get the received data you have to read from the RXFIFO over SPI using burst mode. An simple example of a basic receive and transmit please look at the cc112x software examples:
