Installing a .dwl file from file-system

Legacy Open AT
1

Hi All.

We are using the SL808xT module.

As per the ADL-User guide,

As this service is managed above the file system on the AirPrime SL808xT & Q2698 embedded
modules, it is highly recommended to use the file system service directly instead of the A&D storage
service. However the A&D storage service API is available for compatibility purpose with 2G
products.

Reading the above, we would love to have the following mechanism ::

a)
Download the dwl-file-bytes from internet, and keep storing the dwl-file-bytes on the file-system on the fly.

b)
Once the download is complete, use an equivalent function of s32 adl_adInstall ( s32 CellHandle );

where CellHandle could somehow be mapped to the dwl-file stored on the filesystem.

Is this even possible? Am I being too hopeful? :slight_smile:

Would love to hear back from you experts !!!

Thanks and Regards,
Ajay

Hello Ajay,
You can use adl_fsinstall function to install .dwl file which you have downloaded in File system.

Thanks & Regards,

Thanks Rex for the help.

Unfortunately, I could not find any complete-working hello-world program for the same (no sample-program with OpenAT, neither any reference in the ADL-User-Guide).

Following is the code.
Upon execution, it gets stuck at Beginning installation … (even though file energy-meter_maestro-m100-2g_5.5.0_5.5.0.dwl is present on the file-system).

    	info_log(LOG_GLOBAL_BUFFER);

Kindly point me to a complete working example for the adl_fsInstall API, I will be grateful.

Thanks and Regards,
