Working Mode Introduction

1. Network transparent transmission mode

In this mode, User’s device can send data to specified server by LTE network. G780 support 4 socket links. Four links are mutual independence.

2. HTTPD Client Mode

In this mode, User’ device can send/obtain data to/from HTTP server directly. The data will sent to Web server (apache, IIS, tomcat etc) in Http (GET/POST) mode as long as sending data in formal format. User can utilize the scripting language like PHP, ASP as database storage.

3. SMS transparent transmission mode

In this mode, user’s device can send SMS to specified phone number, or send the SMS from phone to device.

4. AT command

Whatever G780 working in any mode, user can send specified command to G780 to switch to AT command mode.
