Problem in Receiving without preamble/sync packets

Other Parts Discussed in Thread: CC1101

Hey All,

 How to configure the CC1101 registers to receive the  packet  without  preamble/sync?

 Thank you very much

  • The package engine removes preamble and sync before the received data is transfered to the RX FIFO. CC1101 needs preamble to settle the AGC and to do bit sync.

  •  

    I used signal  source to sent a package with preamble and sync .And the frequence was 433MHz,modulation was ASK/OOK,date rate was 1.2 kBaud.  The preamble pattern was an alternating sequence of ones and zeros (10101010…). The length of the preamble was four bytes.

    CC1101  could  receive the  package when I chose 30/32 sync word bits detected ,but  it could not receive when I chose no preamble and sync.
