Other Parts Discussed in Thread: TEST2

Hello,

i used for 250kbaud this rx rfsetting: (it works perfect)

   0x06,   // FSCTRL1   Frequency synthesizer control.
    0x00,   // FSCTRL0   Frequency synthesizer control.
    0x23,   // FREQ2     Frequency control word, high byte.
    0x31,   // FREQ1     Frequency control word, middle byte.
    0x3B,   // FREQ0     Frequency control word, low byte.
    0xCA,   // MDMCFG4   Modem configuration.
    0x83,   // MDMCFG3   Modem configuration.
    0x10,   // MDMCFG2   Modem configuration.
    0x22,   // MDMCFG1   Modem configuration.
    0xF8,   // MDMCFG0   Modem configuration.
    0x00,   // CHANNR    Channel number.
    0x34,   // DEVIATN   Modem deviation setting (when FSK modulation is enabled).
    0x56,   // FREND1    Front end RX configuration.
    0x10,   // FREND0    Front end TX configuration.
    0x18,   // MCSM0     Main Radio Control State Machine configuration.
    0x16,   // FOCCFG    Frequency Offset Compensation Configuration.
    0x6C,   // BSCFG     Bit synchronization Configuration.
    0x43,   // AGCCTRL2  AGC control.
    0x40,   // AGCCTRL1  AGC control.
    0x91,   // AGCCTRL0  AGC control.
    0xE9,   // FSCAL3    Frequency synthesizer calibration.
    0x2A,   // FSCAL2    Frequency synthesizer calibration.
    0x00,   // FSCAL1    Frequency synthesizer calibration.
    0x1F,   // FSCAL0    Frequency synthesizer calibration.
    0x59,   // FSTEST    Frequency synthesizer calibration.
    0x81,   // TEST2     Various test settings.
    0x35,   // TEST1     Various test settings.
    0x09,   // TEST0     Various test settings.
    0x47,   // FIFOTHR   RXFIFO and TXFIFO thresholds.
    0x0B,   // IOCFG2    GDO2 output pin configuration.
    0x0C,   // IOCFG0D   GDO0 output pin configuration. Refer to SmartRF® Studio User Manual for detailed pseudo register explanation.
    0x04,   // PKTCTRL1  Packet automation control.
    0x12,   // PKTCTRL0  Packet automation control.
    0x00,   // ADDR      Device address.
    0xFF    // PKTLEN    Packet length.

Now i will transfer the data synchronously with 500kbaud. If i change the baudrate (500kBaud) an the Rx filter Bw (812KHz) in the smart rfstudio. The RF studio says:  Ii should only change the register MDMCFG4=0E. But then the data transmission is very bad.

What should i change? Where can i find some information about the rfsetting for the 500kbaud transmission?
