ACK in case of UDP
UDP is protocol that doesn’t check whether the data is transmitted successfully. So, the device checks
completion of sending with ACK depending on UDP_ACK type.
ACK is sent by server when the data is received.
If the ACK is not sent during more than 2 minutes after sending, the device recognizes the data was not
reached to server and sends the data again.
Examples of ACK report are as below.
String Format : “ST600ACK;850000”
Zip Format : 0x15 0x85 0x00 0x00
It is recommended ACK_TYPE is set to ‘1’ to confirm all data can be transmitted safely.
Report Type UDP_ACK=0 UDP_ACK=1 UDP_ACK=2 UDP_ACK=3
