Posted on October 04, 2016 at 16:58Hi,
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...
