Introduction<\/strong><\/p>\n

AT Command Tester<\/a> application is an online tool for testing AT commands and other module functionalities such as data call<\/a>, voice call<\/a>,HTTP<\/a>, network registration<\/a>, SMS<\/a>, Phonebook<\/a>, signal quality<\/a>, SIM interface<\/a>,  device info<\/a> etc.<\/p>\n

AT Command Tester can be used with  (GPRS\/EDGE\/1x) or <\/a> (HSDPA\/HSPA\/EVDO) or <\/a> 4G modules<\/a> (LTE)<\/p>\n

Configuration<\/strong>
\nConnect the Telit Module (on EVK or Arduino shield) to the PC. AT Command Tester <\/a>tool is typically run on a browser (have been tested on IE, Firefox and Chrome).<\/p>\n

1. Enable AT Command Tester to communicate directly with the Telit Modules.<\/p>\n

2. There have been some issues observed with AT Command Tester when used in autobaud mode. So change the port speed as follows,
\n– Press ‘Find Ports’ and connect to the arduino port.
\n– If the connection is successful, the device model info will be displayed.
\n– In the ‘Command Mode’ tab, send the following AT command
\nAT+IPR=38400
\nOK
\n– then disconnect and connect again with the baud rate set to 38400 on the AT Command Tester.<\/p>\n

Command Mode<\/strong>
\nIn the ‘Command Mode’ tab of the AT Command Tester, any AT command can be sent to the modem. The drop down in that tab has the list of 3GPP specified AT commands.<\/p>\n

\"\"<\/p>\n

Script Mode<\/strong>
\nIn “Script Mode’, users can send multiple AT commands at a same time. You can create your own script and store in on your local machine. Saved scripts can be loaded and executed at a later time.<\/p>\n

\"\"<\/p>\n

Diagnostics<\/strong>
\nIn diagnostics tab, you can get useful modem information such as manufacturer info, signal strength, registration status, connection status etc.<\/p>\n

\"\"<\/p>\n

Data Call<\/strong>
\nGPRS modems uses Packet Data Protocol (PDP) contexts to establish data calls. PDP contexts are stored on the device and has information about the carrier APN, PDP type etc. AT Command Tester <\/a>provides easy to use interface to add\/edit PDP contexts. Users can also activate or deactivate a specific PDP context. AT command tester checks whether the device is registered with the network <\/a>before establishing a data call<\/a>.<\/p>\n

SMS<\/strong>
\nAT Command Tester provides easy to use interface to send and receive SMS messages. Currently only text mode is supported. SMS message format can be PDU or Text. So before using the SMS tab, please set the SMS message format to text mode by sending the following AT command in the ‘Command Mode’ tab.<\/p>\n

TCP\/UDP<\/strong>
\nTelit’s GR863-GPS module provide sockets to setup TCP or UDP connections. There are up to 6 sockets avaialble that can be configured differently. Sockets use the PDP contexts to establish a TCP or UDP call.AT Command Tester provides interface to read the configuration and the status of all sockets. Users can also activate ot deactivate a socket.
\nThen users can establish a TCP or UDP connection to a remote server using the AT command tester. Once a TCP or UDP connection is established through a socket, users can use other application services such as HTTP, FTP, SMTP etc.<\/p>\n
