Actually smaller buffers would be better, but largers buffer don't tax the USB transfer so much (the transfer stays for longer in the kernel). This might have to do with the high sample rate you use. At the default size of 262144 the usual 250k means 2 buffers/s (~500ms), at 2048k would be 16 buffers/s (~60 ms), with the larger buffer you are back to 4 buffers per second. Or it could be that processing in rtl_433 takes longer than the buffer interval and that might get things stuck. Could you test please by disabling all (FSK) but one OOK protocol, e.g. |

Without arguments is the default 250k -- that should always work. |

I got a bunch of DSC Security Contacts (EV-DW4975) which should be supported by rtl433. I opened a contact, placed in a new coin cell (just in case). Then I plugged my simple RTL2838 into the usb port and started rtl433:
I then move the security contact and expected to see something. But nothing. I went just a few cm close to the antenna and repeated. Nothing.
Is there anything else required? How do I go about debugging this?
