Thank you MIchael, I will try with short and see the results. I must express my appreciation for the work you and Mark did on this framework - the V3 feels ages ahead of V2 and the boot time, the wifi possibility both AP and client, the terminal on usb, the programming via usb... it is just pleasure to work with. Thank you again!
