Dear Vekexasia,

I found that you tried to decode a Bresser 5 in 1 weather station with a cc1101 Module.
Thanks a lot for your code and the well written documentation.

I tried to adapt your code for my basic needs:

Used Processor:
ESP32 TTGO Mini V2 Board

But I am always running into some decoding issues:

So you have any Idea what i need to change to get proper decoder values?
Is there any advise you would recommend for changing deviation?

Console Output:

I am wondering why I can decode the PreAmble 0xAA, 0x2D, 0xD4 always correct... but stuck in the CRC Check and the data.
I tried already the sent example code and checked in an SDR if the frequency looks similar... somehow I am stuck and have no idea anymore
