Hi all,

with theline like this :

'fremde IP Adresse
Result = Udpwrite(f_ip , F_port , Sockel , "Test")

i can send to the Adress and Port there is in the var f_ip , and f_port, on the Socket there is in the var Sockel.

Thats work fine but only one time. Will say after i have send to the adress, the adress is fix. Never i can send to a nother Adress. I dont belive it , but its true. the Adress in the var:F_ip is not the destination Address, the paket come not to the destination.

The Reason is i have 2 Computers connect to the MCU and both sending a Question to the MCU , and the MCU shout give a Answer to the both Computers. But it sending only to one (the Computer thre was first Connecet to the MCU).

Is this normal or wrong. Have one of You a Problems like this. Need Help/info or a Workaround. Mabee the Problems is on me, so tell me more.

Thanks

Just an Idea:
Could it be, that you only use one socket? And when the first PC opens that, the second doesnt get a connection and thus no answer.
