Once you start playing with Software Defined Radio (SDR), you see targets to look at everywhere.. thanks to @jwildeboer for bringing these Lora devices into the office!
The signal looked strange at first, as if the HackRF with the 20Mhz bandwidth it can monitor in parallel could not grasp the full signal.. that was because it was so strong. Taking off antenna and playing with gain improved things.
