There is an issue I can't solve with LED&KEY tm1638 hardware. The configuration is Arduino Nano with 2 tm1638 LED&KEY modules. Everything connects fine and works with Simhub, but only in Single Arduino mode. When I switch to Multiple Arduino mode, LEDS on tm1638 stop responding. They don't light up at all, I tried to choose all colors, green as well, nothing helps.

Maybe it's a simhub software problem? Can anyone tell me how to fix it?
