no data from temperature sensors #11

thanks for the great program, well done! after setting it all up I don't seem to be getting any data from two temperature sensors (Oregon Scientific RMR382 and Ea2 AL802):

pi@bereskapi-ha:~/nexus433 $ sudo nexus433 --verbose -n 17 Loading configuration from /etc/nexus433.ini Reading data from 433MHz receiver on /dev/gpiochip0 pin 17. Decoder resolution: 1 µs; tolerance: 300 µs Connected to MQTT broker.

how can i debug this? are my sensors not nexus compatible?

thank you

found this: http://wmrx00.sourceforge.net/Arduino/OregonScientific-RF-Protocols.pdf it mentions Manchester coding no dice?

If you have logic analyzer e.g. Saleae you can just connect to 433MHz receiver data pin and see what's going on. If not, you can add printf("1"); in line 108 and printf("0"); in line of decoder.cpp (and printf("\n"); in line 68 ) to see if any bits are decoded. Make sure you got power and data line properly connected and the sensor is close to the receiver (to make sure signal is good enough). If you properly connected everything most likely the sensor is not compatible with nexus protocol (I have no idea what protocol they're using).

Just saw you comment about manchaster coding. That definitely means sensor is not compatible.

ah, very sad( looks like I'l have to try rflink or similar I have a HackRF One) but I'm still very new to rf world
