Error in UDP when sending Bytes

Good Morning Everyone,

I am trying to send Bytes from one node to another.I have tried all variations of fprintf , sprintf but get some or the other error all the time. Here is my Code :

udpa = udp('192.168.2.8',7090,'LocalPort',7091);

fopen(udpa)

TheTime = now;

dv = datevec(TheTime);

dv(6) = 0;

reconstructed_time = datenum(dv);

timediff = TheTime - reconstructed_time;

diff_secs = timediff * 24*60*60;

s = sprintf('Master node sent Sync Message at Time %s%09.6f', datestr(dv, 'yyyy-mm-dd HH:MM:'), diff_secs);

Bytes = uint8(s);

s1 = sprintf(udpa, Bytes) % error is in this line : too many output arguments%

fclose(udpa)

delete(udpa)

Post Script: I am already able to send messages and time to another node via fprintf but not able to get through Bytes somehow. Most of the times , i also witness an error of

Adress already in use Error UDP Socket fopen() . I would appreciate any help :)

Kind regards
