PUBLISH message sent from server

[kushal bhattacharya]

I am having  some trouble  regarding  implementing  the algorithm  when suppose the server sends 2 publish message of same topic  to the  same client  in  that  case  what  would  would  the  behaviour from  server  and  client .Presently when  i am sending  2 PUBLISH messages from  the server  the paho  client is responding  to the last PUBLISH message

i mean   do i have to  put  some delay  in  between  the  2 PUBLISH messages  from  the  broker  end ,i dont  know  am not really  not in  that  idea but still am  having this idea

Have you explored the DUP flag of the PUBLISH packet? I am not sure, I understand your case; but, you might want to take a peek into the PUBLISH packet for DUP. http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc398718037

when  i  am  sending data  from  the broker with  qos   1  there  is no  packet  loss  on  the  client  is  it   advisable  for  fast  communication   that  i can  use  qos  2.In  some  blog   i  read  that  due to  its  three  way  communication (arised  from PUBLISH message)   the  communication  may  become  slow  and there may  be packet  loss

The scenario  is  i am  sending sensor data  from  paho  clients at fast intervals to  the   broker  and  then  i have  applied the  necssary  parsing  mechanisms   on  the  broker  side  in  order  to  prevent  any remaining packets  to be  processed  by the  broker
