    perastaja
    Hello, I am trying to get the CC1101 and CC1020 to communicate. Both modules should use the following settings: GFSK modulation, 1.2 kBaud data rate, 430.8695 MHz frequency and Manchester coding. I have programmed both modules with these parameters but so far I haven't been able to send or...

    Hi nick836, First to clarify the issue with the xtal running or not. The easiest way to check that it is running is to check the output on GDO0 after reset. It's default output is CLK_XOSC/192. To verify that the chip is ready, check GDO2 after reset. GDO2's default output after reset is the...

    Hi Champs, There seems to be an inconsistancy within the CC1101 Data Sheet. Could someone please comment on the following observations? Looking at the CC1101 data sheet (SWRS061D), table 3 lists the minimum baud rate as 1.2kbaud. Later on, table 22 says it can go as low as 0.8kbaud. Playing with...

    I am using WOR with 6% duty cycle or lower with Event0 of below 200msec. The base station (transmitter) is transmitting every 1 sec. The WOR is ideally to be able to detect the present of the base station and respose with its ID. However, when tested, the WOR response time is more than 10sec to detect...

    I am using CC1101 on 250kBaud, but when I change the data rate from 250kBaud to 1.2kBaud, the radio doesn't work. I change the register value from SmartRF. Does anyone know how to change the data rate of CC1101, and where can I find the value of register on 1.2kBaud Thanks

    Occasionally, after transmitting or receiving a packet, the RXBYTES register shows an "impossible" value, like 92, 98, 121... That is, the overflow bit isn't set, but the NUM_RXBYTES value is far more than the 64 byte maximum. The value is consistent, too: repeatedly reading the register...

    In some of our applications, we use low power listening (http://www.tinyos.net/tinyos-2.x/doc/html/tep105.html) for power management. Basically, this turns the radio on every interval (50 ms in the current application) and checks for a carrier (by checking GDO2, IOCFG2 = 0x09). If there is none, the...

    Hi Jon, It seems to me that there is something wrong with the way you write to the txBuffer array. You should check what values you actually write to the TXFIFO register and what you read out of the RXFIFO on the reciever.
