I can confirm Sara’s idea to wait before the marking and not during seems to be more reliable, I had an issue where (rarely) the sensors did not answer to a measurement request, this seems to fixed this.

It is hard to be 100% sure about this since it doesn’t happen often but it seems to be better this way, and since it is also SDI-12 spec…[Read more]

I did not try to add it while at at “break level”. That is true, I missed this in the spec.

I’m guessing most (if not all) SDI-12 sensors wake up on a rising edge then start their timers from their. I think it will work all the same while respecting the SDI-12 spec.

I’ve actually got a few sensors now. As soon as I’ve got the hardware to drive…[Read more]

I left it at the “marking” level. Here is your typical CS215 SDI-12 frame with said modification to the lib. I think this is an ADDR request (I decoded it but can’t find my notes anymore).

Hi,

As it seems the Enviro lib still have the same problem with the CS215, I think I actually found a fix, so i wanted to share it with you guys.

I’ve updated the Arduino thread linked in the first post. But I’ll put the same explanation here:

The Enviro lib does not fully respect the SDI-12 protocol. There is one important timing aspect which…[Read more]
