21 Network Time Client Network Time Client iChip incorporates a Simple Network Time Protocol (SNTP) client. With this protocol support, iChip can be configured to check SNTP servers for current time and date each time it goes online. iChip is configured to retrieve time data from a Network Time Server each time it goes online with the NTOD parameter. After updating its internal Time-Of- Day (TOD) registers at least once, iChip continues to keep track of time independently, even after it goes offline. When iChip contains real TOD data, e-mails sent are automatically stamped with Time and Date of delivery, according to RFC (822) definition for the date header field. In addition, the AT+iRP8 report returns the current time and date. iChip also contains parameters to configure local GMT offset and a DSTD (Daylight Savings Time) rule. These parameters allow iChip to determine the local TOD. When iChip is configured for TOD retrieval from a Network Time Server, iChip automatically retrieves an updated time reading every two hours while online. This configuration improves the long-term accuracy of its internal time management.
22 MIME Encapsulated E-Mail Messages 22.1 iChip-Generated Binary Message Formats MIME Encapsulated E-Mail Messages Binary e-mail messages are sent via iChip using one or more AT+iEMB commands. The message format is limited to an optional body of text and a single attachment. The following fields are added by iChip to the main message header: X-Mailer: iChip Message-ID: @iChip Mime-Version: 1.0 Content-Type: multipart/mixed; boundary=”CONE-iChip-” The message‘s preface contains the following text: “This MIME message was coded by iChip.” If the host application includes a text body for the message, it also contains the following lines in its header: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit X-iCoverpage: Email When no textual body contents are included – this section is omitted. The binary attachment section follows, beginning with a MIME attachment header containing the following fields: Content-Type: /; name= Content-Transfer-Encoding: base64 where, := ―text‖ / ―image‖ / ―audio‖ / ―video‖ / ―application‖ := := or defaults to ―application‖ when otherwise not defined. defaults to ―octet-stream‖ when otherwise not defined. Following the header, a base 64-encoded data stream includes the entire binary data transferred to iChip from the host. 22.2 MIME-Related AT+i Commands and Parameters Binary images are transferred to iChip for MIME message encapsulation via one or more AT+iEMB commands. An AT+iEMB command sequence must be terminated by the AT+iE* command, indicating the end of the binary e-mail message. When several consecutive AT+iEMB commands are used, the host must issue the commands with an inter-command delay, which does not violate the SMTP server‘s timeout constraints. Otherwise, the SMTP server will timeout and abort the session. Average SMTP servers allow for delays in the range of 30 to 120 seconds. Additional
