[SOLVED] Gateway RS485
-
@philippe-57 do you have any idea how SoftwareSerial could work when there was an error on the PCB?
@mfalkvidd yes I said it works with the test sketch and I do not know why, what I saw on my PCB is that the frame go in one direction and that's why with mysensors the gateway was not answering
order placed for new PCBs, waiting now

Hello everyone
I found my problem, it comes from my PCB there is an error on the tracks, I ordered again corrected PCB and I come back to you when I could do the tests. it takes at least 15 days / 3 weeksthanks again for your help i get back to you as soon as possible
And why wait 3 weeks for new PCB?
Simply cut bad connections on PCB a and make correct connection with wire.And four RS485 connectors on gateway?
RS 485 is bus - from one node to next, all in one line.
Not star topology.
If you plan connect four nodes with 20 m of cable to those connectors - you will be in troubles.
Gateway must be connected like other normal nodes. Only sw is different.
