hi sir,
we had developed a product using RF cc1101.
Problem:
Some of the rf modules (RF cc1101.) was not working.
We having a transmitter and a receiver has configured using the below settings
#define SMARTRF_RADIO_CC1101
#define IOCFG2 0x09 // do not change
#define IOCFG0 0x06 // do not change
#define FIFOTHR 0x47
#define PKTLEN 0x05 // do not change
#define PKTCTRL1 0x08 // do not change
#define PKTCTRL0 0x44 // do not change
#define CHANNR 0xFF
#define FSCTRL0 0x00
#define FSCTRL1 0x08
/**
* 335 Mhz
#define FREQ2 0x0C
#define FREQ1 0xE2
#define FREQ0 0x76
*/
/** 433 Mhz
*/
#define FREQ2 0x10
#define FREQ1 0xA7
#define FREQ0 0x62
#define MDMCFG4 0xF5 //f5 1.2kbps
#define MDMCFG3 0x83
#define MDMCFG2 0x02 //16/16 sync word bits detected
#define MDMCFG1 0x20
#define MDMCFG0 0x00
#define DEVIATN 0x15
#define MCSM1 0x30
#define MCSM0 0x18
#define BSCFG 0x6C
#define AGCCTRL2 0x03
#define AGCCTRL1 0x40
#define AGCCTRL0 0x91
#define FOCCFG 0x16
#define WORCTRL 0xFB
#define FREND1 0x56
#define FREND0 0x10
#define FSCAL3 0xE9
#define FSCAL2 0x2A
#define FSCAL1 0x00
#define FSCAL0 0x1F
#define RCCTRL1 0x41
#define FSTEST 0x59
#define TEST2 0x81
#define TEST1 0x35
#define TEST0 0x09
When the rf C1101 modules has replaced by another module it was not worked.
I had read back the register’s from rf chip has same setting for every modules, but it was not responded to the transmitter.
