\
**Acknowledgment :** \
The device firmware expects an acknowledgement string **"logid"** by default, because thats what we use in our server. You can change it to whatever value you like. Its in XHTTP\_Request function.\
For google scripts it expects response value as **"Moved"** . \
\ <mark style="color:red;">If it doesn't receive the acknowledgement text, it will keep repeating the packets.</mark>&#x20;
