I was starting from multi-NUs.I need  to send form a Master  a message to 4 Slave  every 50mS.

I see that up to 100ms It work  but that at 50mS the comunication doesen't work .

I have to send 30 bytes is there a minimum time required to send the message? 10ms per slave are not enough?

Best Regards
