  • Forum Post: CC253x Family Sleep Mode

    KrAmBrO
    HI there, With the CC253x family I noticed there are no WOR modes. What is the best wakeup method when the device will only be receiving information maybe 2-3 time a day for a short period of time <1sec. Is there a method other then the sleep timer to wake up (i.e where the CC253x can wake up on...

  • Forum Post: Crystal for CC2500 not turning off

    Adam Karkowski
    Hi all, first post here. I'm not sure if this is the correct sub-forum for this question but here goes... I'm using the CC2500 with a 26 MHz xtal and it works (mostly) fine. Send and receive works as expected. I'm running the CC2500 in Wake-On-Radio mode which seems to be functioning...

  • Forum Post: cc2530 "wake on radio" ability

    Shi Edward
    I learn from the product list that cc2530 has the ability to "wake-on-radio"(WOR). But I couldn't find any resource related to cc2530 describing this. I'd like to know whether cc2530 is supported by WOR and how I can work with it. Thanks for your reply!

  • Forum Post: Re: Repeated packet transmission with CC1101

    Firefighter
    Hi again, Yes, that is my suggestion. The RX_TIME bits set the timeout for sync word search in RX for both WOR mode and ordinary RX operation. When using WOR mode, RX_TIME can have a value between 0 and 6 when WORCTRL.WOR_RES = 0, and between 0 and 3 when WORCTRL.WOR_RES = 1. RX_TIME = 7 means...

    Hi, If RX_TIME is between 0 and 6 you will timeout unless you find a SYNC WORD (not preamble, to be exact). If you find a SYNC WORD you will receive that packet. Preamble is used for bit sync while sync word is used for byte sync of the data. //Jonas

    Hello, I'd like to clarify two things that I found out in the last two days for any interested reader... 1- it is possible to send packets back to back setting the TXOFF_MODE in Stay in TX (Start sending preamble); send the first packet, then: - wait for the GDOx to de-assert (in case...

  • Forum Post: Can i use only a carrier to wake up CC1101?

    Ushan Karunathilaka
    Hello TI experts, I m using CC1101 in my design and i want it to wake up during WOR mode. I m using GFSK modulation. Can i wake it up by only transmitting a carrier, if YES, how to set the CC1101 to transmit only a carrier? Thanks, Ushan

  • Forum Post: Re: CC1101 Selective wake up using WOR

    Martin B
    Hi The most important feature of the sync word is the byte synchronization, so the autocorrelation feature of the sync word is important. To avoid numerous equal bits in a row, espessially for addresses 0x00 and 0xFF, I would consider spreading the address bits over the entire sync word, See latest...

  • Forum Post: CC1101 WOR cycle limit

    Nad Gilbert
    Hello all, I think I might have found a potential bug in the WOR mode in the CC1101. It appears that after a ~1k WOR cycles without any interups the CC1101 will automaticly go to the Idle state. Has anyone else seen this? Are there registers setting that will prevent this? I currently have the EVENT0...

    Ushan Karunathilaka
    Hello TI wireless experts, In my wireless application i m using CC1101 i m using star topology with maximum of 256 child nodes per parent. To wake up the child nodes, i m using WOR. It would be better if i can incorporate "Selective wake up" somehow. Therefore i have used individual...

  • Forum Post: Confusion about PQI and Sychron for WOR usage

    Dushan Balisson
    Hello TI experts, I am starting development with the CC1101, my confusion is as follows: By setting the RX_TIME_QUAL = 1 in MCSM2, If PQI is set due to noise "assumption" and there is no sychron afterwards, does the chip goes back to WOR or does it go to the IDLE state. Thank you in advance...
