CC113L: Two-byte synchronization code is set, and the receiver side has a garbled issue

Part Number: CC113L

Hi team,

Issue: four different byte synchronization codes are set on the transmit side, two byte synchronization code detection is set on the receive side using CC113L, and garbled on the receive side.

The customer would like to know what is the reason,  are there any receive routines?

The following are the register configuration parameters:

static const registerSetting_t preferredSettings[]= // should change to CC113L reg
{CC113L_IOCFG2, 0x06},
{CC113L_SYNC1, 0x54},
{CC113L_SYNC0, 0x21},
{CC113L_PKTLEN, 0x32},
{CC113L_PKTCTRL1, 0x0C}, //
{CC113L_PKTCTRL0, 0x05}, //
{CC113L_CHANNEL, 0x00},
{CC113L_FSCTRL1, 0x0C},
{CC113L_FREQ2, 0x10},
{CC113L_FREQ1, 0xAA},
{CC113L_FREQ0, 0x59},
{CC113L_MDMCFG4, 0x2D},
{CC113L_MDMCFG3, 0x3B},
{CC113L_MDMCFG2, 0x02}, //
{CC113L_DEVIATN, 0x57}, //
{CC113L_MCSM1, 0x0C}, //
{CC113L_MCSM0, 0x18},
{CC113L_FOCCFG, 0x1D},
{CC113L_BSCFG, 0x1C},
{CC113L_AGCCTRL2, 0xC7},
{CC113L_AGCCTRL1, 0x00},
{CC113L_AGCCTRL0, 0xB0},
{CC113L_RESERVED_0X20, 0xFB},
{CC113L_FREND1, 0xB6},
{CC113L_FSCAL3, 0xEA},
{CC113L_FSCAL2, 0x2A},
{CC113L_FSCAL1, 0x00},
{CC113L_FSCAL0, 0x1F},
{CC113L_TEST0, 0x09},

Could you help check this case? Thanks.

Best Regards,


  • Hi Cherry,

    The situation is not clear to me. Can you post the specific sync code used on each side?

    Can you describe the issue they are seeing in more detail? What specifically are they receiving or not receiving?
