ACK in case of UDP
UDP is protocol that does not check if the data has been transmitted successfully. So, the device checks
completion of sending with ACK depending on UDP_ACK type.
ACK is sent by server when the server receives the data.
If the ACK has not been received for more than 2 minutes after being sent, the device recognizes the data has
not been reached to the server and sends the data again.
Examples of ACK report
are as below.
String Format : “
ST300ACK
;100850000”
Zip Format : 0x150x10 0x08 0x50 0x00 0x00
Device users are recommended to set
ACK_TYPE to ‘1’ to confirm that all the data can be transmitted
successfully.
Report Type

UDP_ACK=1
