Thx for the answers gbafamily.
Okay now i can send 8 Pakets within a second. Great but the problem is i ned more, exactly i need 100.
now my questons are:
1. Is this posible to send 100 or more packets with 5 Byte within a second.
2. Is there any documentation who can I read what the maximal package rate is. (in real workspace)
3. Is it better to use a RTOS to send more packets in one second.
The for your attention !
