Spirit1 / SPSGRF receive

Question asked by Loïc Bouilly on Oct 4, 2016
Hi,

I use the SPSGRF module in 868MHz Narrowband. I search to send packet with this configurations : 
- Fc = 869.2375MHz
- Fdev = 2.7 kHz
- Datarate = 4.8 kBit/s
- Number of channels : 0
- Spacing channel : don't care ? 
- Modulation : GFSK_BT05

So for my receiver a set : 
- Channel filters : 11,0 kHz  > (2*Fdev + datarate) ~ 10,4KHz
- SQI / PQI : Disable 
- RSSI Threshold : -20 dBm.

In this configuration I receive nothing. In my Spectrum analyzer, I see a signal when I transmit something, but receiver doesn't see : Preamble, Sync Word ...

So which parameter I miss to configure for make a reception ? Something hide ?
Or it's my transmit who is no good ? 
I think is not channel filter the problem... 

Regards,
Loïc
