I am new in this group, and I would first like to say thanks to this community, I have used the Stack groups to solve many many questions I have, so it is a powerful knowledge place. So thanks for this.
I am using a RFM98PW module, and I would use it in narrow band, 12.5 kHz. I am able to work with it in 25 kHz bandwidth, but when I try to use it in 12.5 kHz, something doesn't work. I tried with 5 kHz Fdev, and 20.8 kHz BWRx,and 19.2 kbps and I need to down to 12.5 kHz, but when I set the Fdev to lower values, I can see it perfectly in the Spectrum analyzer, but the link with other module doesn't seem to get any packets. (Fdev 3.05 kHz, BWRx 12.5, Bitrate 9.6kbps). Does anybody tried it? If so, I will have a deeper look into my settings.
Many thanks in advance Jordi
