@Serj-Sam there is a pull request included in that pr. Once this is merged it will be available in development, later in the next release.
If you just downgraded the core, that is persistent until you upgrade the core to 3.x again.
@gryzli133 I have a number of MySensors devices using RS485, it would be interesting to try to run PJON protocol over RS485, it seems like there is such an opportunity, but I could not figure out how to use it in the MySensors library.
@BearWithBeard No need to say sorry! You did point me to the right direction, I was clueless
I've tried a different RS485 DE pin, but still no luck.
#define MY_RS485_DE_PIN 4
I've seen people mentioning RS485 transport here in the comments but I'm not sure if anyone actually did test this combination (RF24 & RS485).
@Michiel-van-der-Wulp There was a discussion early this year 2021 on this issue,
see: Contribution Issue with CLA and clahub.com
But unfortunately there is no feedback for a solution from the core team for now.
@lood29 That is correct, assuming the same radio technology is used. Typically, you set up a separate gateway because you want to run a sensor network on a different radio family due to longer distances or similar.
