Constant interrupts #21

Hi,

I'm trying to get this library working on my D1 mini (esp8266). I've tried with RXB6 and MX-RM-5V. While I don't have Digoo DG-R8H yet, I was hoping to make some progress with an EMOS temperature sensor.

But the issue I'm having is that interrupts are being generated constantly, regardless of whether it's RXB6 or MX-RM-5V. There doesn't seem to be any packet validation, so the serial console keeps displaying nonsense:

If I get it right, interrupts should be generated only when the pin changes from 0 to 1 or from 1 to 0. The fact that interrupts are generated constantly suggests that something is transmitting all the time which I think is simply impossible.

Any ideas what my problem is?

Thank you.

Hi

If the radio you used is very sensitive it will pickup all sorts of noise from the environment and this can surely happen.

Thank you for reply. What can I do in such case? Try to search for some patterns? What radio do you use?

Play around with basic filters: https://www.arrow.com/en/research-and-events/articles/using-capacitors-to-filter-electrical-noise

I use a cheap radio bought on aliexpress, some times they are good some time they are rubbish 🤷‍♂️
