issues in decoding data

[stutm]

Hi everybody,
i am targeting a device that operates at 869.4Mhz, bandwidth 8, Spreading Factor 8. I am using a HackRF.
I am trying to decode LoRa data and I am receiving (this only happens when using 869.5 instead) just incomplete parts.
I am attaching the graph. Please help ?

The data received
