CC1120: 发送字节超过128字节,应该怎么操作?

Part Number: CC1120


    rc = trxSpiCmdStrobe(CC112X_SFTX);

    if (s_TxLen != BuffLen)
    {
        s_TxLen = BuffLen;
        cc112xSpiWriteReg(CC112X_PKT_LEN, &s_TxLen, 1);
        Lg_printf(LG_CRT, "CC112X len = %d\r\n", s_TxLen);
    }
    
    rc = cc112xSpiWriteTxFifo(DataBuff, BuffLen);
    rc = trxSpiCmdStrobe(CC112X_STX);

	while(IO_IN_VAL(5, 2) != 0);

现在我调试的1120只能发送128字节以内的数据,数据包超过128字节之后,就发送不过去,有没有什么办法,可以使1120发送128字节以上的数据?
