Transponder registration to base station (Random IDs)

[dmitrylambert]

Hello,
I've deployed transponder v0.3 based on schematics, uploaded the code of v0.3 where changed only Transponder ID.
Restored raspberry 3 from image, launched ./ir_daemon
But on the web page, I see that "Last registered ID" randomly changes from 1 to 36 despite the fact that I am using just one transponder with id=1
If I run daemon with enabled debug I can see the same, that each time i point transponder to receivers, 9 bits are always different.

Any ideas why this could be happening?
