packet sniffer configuration with CC1111 devices

Other Parts Discussed in Thread: CC1101

I have a configuration for the CC1101 that I would like to use with the sniffer using smartRF however getting the configuration to work perfectly seems to be a arduous (trial and error). Is their a clean way to do this? I have a configuration I did before but frequency etc has changed. It would be VERY helpful to be able to take the smartRF configuration for a CC1101 (26mhz) and mostly migrate it to the CC1111 without guessing at settings.

It seems a bit too much trial and error to migrate the configuration. I prefer to do so in a more effective (efficient too) manner. As I have numerous frequency allocations etc. I have to deal with and this... is a pain to do for each change.


Suggestions very welcome (and yes I've already attempted to do it a few times). If necessary I can post my smartRF configuration for the CC1101 and the C1111 etc.


Thanks

    Here is the smartRF configuration used for the CC1101

    // RX filter BW = 541.666667 
// Sync word qualifier mode = 30/32 sync word bits detected 
// CRC enable = true 
// Preamble count = 4 
// Data rate = 249.939 
// Manchester enable = false 
// Data format = Normal mode 
// Whitening = false 
// Packet length = 255 
// Modulation format = GFSK 
// Channel number = 0 
// Deviation = 126.953125 
// Address config = No address check 
// TX power = 0 
// Base frequency = 904.149841 
// Packet length mode = Variable packet length mode. Packet length configured by the first byte after sync word 
// PA ramping = false 
// Channel spacing = 231.689453 
// CRC autoflush = false 
// Modulated = true 
// Carrier frequency = 904.149841 
// Device address = 0

    And the configuration I was "tryng" to use with the packet sniffer (CC1111)

    // Channel spacing = 232.177734 
// Preamble count = 4 
// RX filter BW = 600.000000 
// Deviation = 128.906250 
// Sync word qualifier mode = 30/32 sync word bits detected 
// PA ramping = false 
// Modulated = true 
// Packet length mode = Variable packet length mode. Packet length configured by the first byte after sync word 
// Manchester enable = false 
// Modulation format = GFSK 
// Packet length = 255 
// Address config = No address check 
// CRC enable = true 
// Channel number = 0 
// Base frequency = 904.149902 
// Carrier frequency = 904.149902 
// TX power = 0 
// Whitening = false 
// Device address = 0 
// Data rate = 249.756
