Hello everyone,

i am looking for people who worked with pymodbus on omega2+, i need some help

At this moment, i think my problem is hardware-related, actually i broke my expansion dock and i did some tricks to use it again, i thaught it worked but since then he's not seeing the ethernet dock, and when i power the expansion dock the led is green (usually it's red)

even after setting an ip to the ethernet and disabling the firewall, it doesn't ping .

the output of ifconfig and ping 192.168.0.3 :

omega2+ is directly connected using ethernet cable and the device doesn't run a dhcp, how to set a static ip on the omega ?

yes that's true it doesn't ping anymore
here are my outputs :
service firewall stop

ping 192.168.0.3
nc 192.168.0.3 502
route

ifconfig

The output of route command !
