27.5 Parameter Tags
iChip and host real-time parameters can be referred to in the embedded websites through
the use of Parameter Tags. When Parameter Tags are placed in an HTML web page,
actual values are sent by iChip‘s web server component when the page is served out.
Parameter Tags are also used to change corresponding parameter values from a remote
web browser. Syntactically, Parameter Tags are parameter names enclosed between two
(~) characters. If the (~) character needs to be included in a Web page, two consecutive
(~) characters must be used (~~).
The iChip Internet configuration parameters defined in the AT+i API retain their name
when used as Parameter Tags. For example, the value of the TOA AT+i parameter (Send
to E-Mail Address) may be referenced in the website by ~TOA~.
Host Parameter Tags defined by the parameter name <param>, may be referenced in the
website using ~<param>~. <param> can be any freeform parameter name consisting of a
single word that does not include blanks or iChip delimiters. For example, a parameter
reflecting a temperature reading can be called temperature and referenced in the website
as ~temperature~.
27.6 iChip Configuration Mode
iChip configuration entails monitoring and updating iChip parameter values. By making
use of iChip‘s inherent configuration website, an iChip device can be configured
remotely using a standard web browser in addition to being configurable locally using the
Ymodem protocol over the serial link, via PSTN in a modem environment, or remotely
via e-mail. The iChip
RPG parameter is used to password-protect remote iChip parameter
updates. See Security and Restrictions.
The configuration site includes web forms to monitor and update most iChip parameters
and an upload page consisting of file upload forms. Note that, the following iChip
parameters cannot be configured remotely and are therefore not displayed on iChip‘s
configuration website:
WiFi security parameters
Fast USART parameter (BDRD)
Analog-to-digital converter (ADC) parameters
Each upload form allows file uploading using the POST method for a single file. The
forms support uploading the following files:
Firmware update *.imz file
Parameters update *.rpf file
Packed application website *.img file
When new firmware (*.imz file) is uploaded to iChip, iChip submits an acknowledgment
page to the browser, after receiving the complete *.imz file, and then goes offline and
updates its firmware.
In some rare cases, iChip‘s internal configuration website may be accidentally corrupted.
This happens when iChip fails to complete a remote firmware update process via web. To
