It isn't very scientific, but I think the range is roughly equivalent to a BT832. I can reach my gateway from everywhere in my house except the far corner of the basement, same as the BT. That corner is behind a chimney an lots of plumbing -- RFM69 territory. Maybe the BT832F would work there. Haven't tried those.
After fixing a missing trace on my dev board (my fault, not Oshpark's), and updating my J-link and bmp software. I am able to program these.
I popped the shield off of one just to confirm I ordered the right version. The part numbering vs processor is not very clear on Aliexpress. No surprises there.
@mmartins if you re-read what I wrote, you’ll see that the Raspi-Rollo software has an Arduino sketch to identity the codes. I ran this on a NodeMCU, so it should work on an ESP32.
If you need to use Audacity then the process is well documented in the links earlier in this topic.
I have three blinds and they all use independent remotes and each blind has its own codes.
I’m not sure how my codes will help with yours, but here are the codes for one of my blinds:
If your blinds do actually use rolling codes the I don’t think you’ll be able to control them the same way that I do.
