Long distance (not so long) issue?

[skillsfactory]

Hello,

I've tested your library on a breadboard with 4 sensors and 3 BUS because I've different distances. In my real environment I can find the two closest sensors but not the two farthest (about 20 m on a single BUS). I used an alarm BUS cable for the connections and with the original library I can reach them without particular problems, problems that I find instead on the two closest sensors, so I decided to try this other library... Do you know the maximum distance that can be reached with this library? Thanks Luca

you may need stronger pullup, 4.7k is standard so if you try 2.2k or less to check if it works with longer distance

I'll try Thank you
