Although marked as “Solved” it’s worth mentioning the characteristics of superregenerative receivers.
As I wrote in my thread RF 433 Mhz on virtual pin doesn’t want to send (with scheduling) but didn’t elaborate, a SRR is by design (or function) very noisy when idle (not receiving). The user metacollin explains it very well on Stackexhange: 433.92 Noise … (last post on the page).
And due to the continuously output of garbage, the function tasked with decoding it will probably get stuck looking for a real signal since it receives all the time. Perhaps it’s my limited programming skills, but using those receivers as more than just stand-alone “print received message and nothing else-program” have been problematic.
My two bits…
