Trouble receiving real-time signals

[leoposc]

Hey, first of all I want to thank for all the amazing work. Your repo is amazing and I am thrilled to use it. Sadly my poor knowledge of digital signal processing lacks too many fundamentals to understand why I can not receive/ decode any frames. I would really appreciate if somebody could look into this and maybe spot any misconfigurations.

My configurations are: -samp_rate: 1M (since my hack_rf one does not suppport a sampling rate of 500k. I tried to make use of the Keep 1 in M block, so I do not modify the oversampling rate, but it did not help.) -center_freq: 868.1MHz

I am using a dragino humidity and temperature sensor for my testing purposes. On my network server I could receive the messages. The server states the following configurations which I applied to my flowchart: -sf: 12 -bandwidth: 125k

The picture I appended is a waterfall sink - captured while the dragon sensor transmitted its first message to the server.
