When I connect an external drive to SXT CPE devices, can I do file delivery to these devices on Multicast basis?
Similar like streaming a Video over Multicast.
I know all the pros and cons of Multicast over WiFi.
No, you cannot. There’s no service in RouterOS that lets you write wirelessly received data to a file.
i need to write a program for this.
You can’t run your own programs inside routerOS.
