Hi datuan2008,
I thought I’d might butt in the conversation. I’ve actually had this tested recently on behalf of a customer. I was able to query the GPS data via TCP port 9494 using a simple TCP client. My MP70 was running 4.8.0. The thing is, you will only be allowed to query 9494 from the IP defined in Remote Server IP 1 located under Location/GPS tab of AceManager. Other IPs will be rejected immediately.
Regards,
Nick
