Downloading a File to the Device
The file URL is set in the appropriate MIB object under the acSysHTTPClient subtree (refer to the subtree objects description for the URL form). The download can be scheduled using the acSysHTTPClientAutoUpdatePredefinedTime and acSysHTTPClientAutoUpdateFrequency objects. It can also be a manual process using acSysActionSetAutoUpdate. In this case (only) and as long as one URL is set at a time, the result can be viewed in acSysActionSetAutoUpdateActionResult. In both cases, the acHTTPDownloadResult trap is sent, indicating the success or failure of the process.
acSysActionSetActionId can be set to any value and can be used to indicate an action performed by a certain manager.
A successful process also ends with the file name in the appropriate object under the acSysFile subtree or in the acCASFileTable or the acAuxiliaryFiles subtree, along with the URL being erased from the object under the acSysHTTPClient subtree.
| ● | The action result (both in the acSysActionSetAutoUpdateActionResult object and acHTTPDownloadResult trap) for the Voice Prompt and XML indicates only that the file reached the device and has no indication on the application’s ability to parse the file. |
| ● | The action result in acSysActionSetAutoUpdateActionResult is reliable as long as only one file is downloaded at a time. |
