Hey,
Has anyone had any problems with the size of files being downloaded over the air? I’m running a Fastrack Supreme with firmware revision R74. Using a modified version of the demo DOTA software I can successfully download and install a 50k file, but not a 90k file. The A&Dsize is 2048.
Does anyone have advice on how to solve this problem?
Thanks,
David
i don’t know how to sole this, but i do not hate the problems you describe.
i’m using the same DOTA example (rewritten to use http),
firmware 7.4a
Q2686
default A&D size (never changed it from factory default, so i don’t know the exact size)
and my files are 100k+
Suggests a problem with your “modifications”, doesnt it?
Can you use the sample unmodified?
Problems with my “modifications”… 
Yes, I’ve looked into that. Using the unmodified sample code gives me the same errors however. Using the unmodified DOTA code, I have successfully installed small programs, such as the Hello World demo code - about 50k - supplied with the Fastrack Supreme. Files of around 85k and bigger apparently download correctly (at least the file sizes match and the download process runs to completion), but do not install, giving an ADL_INIT_DOWNLOAD_ERROR on reboot. The code modification I made were to compensate for problems with the DOTA process that people observed in previous forum posts, and they form the base for libraries for a larger program.
You still have the problem?
If so, could you send me the response code of AT+WOPEN=6. Is it a G memory of Fastract Supreme?
Thank you.
I have DOTA source code that works on firmware 7.3 and 7.4, the code was adapted from one of the Sample Apps into one source file. I’ll try and upload…but the website seems to be holding me back…
Trying to add code…I can’t seem to write the word “W H I L E” in the code so correct the “wile” please. Lots of TRACES and comments are gone because the website doesn’t want to allow “F T P” and a lot of other stuff…
Please type your F T P details in the Constant declarations and use at=dwl to start DOTA

}Forum problems - and workaround - descirbed here: https://forum.sierrawireless.com/t/forum-broken/4278/1
Is it possible to examine the contents of A&D memory. I can’t seem to send it out over the serial port fast enough when it arrives over File Transfer Protocol however. Does anyone know the memory address of the A & D cell that the file is stored in?
zafer:
The command:
at+wopen=6
gives the response:
+WOPEN: 6,2048,3072
The command:
ati3
gives the response:
R74_00gg.FSU005 2120060 041709 19:18
which indicates G memory I believe.
charlvz:
Thank you, I’ll try it.
Look in the ADL User Guide - there is a function that gives a pointer to it…
Hi there,
I had a similar problem. I was using G memory Fastract Supreme with the firmware R71.b. I just format the AD space by AT+WOPEN=6,X command where X grater than my application size. Then my problem was solved.
So can you execute AT+WOPEN=6,2000 command on your module just to format your AD space. Then try DOTA again.
Thanks.
At last it works. After checking the contents of the A&D space to confirm that the files downloaded correctly and trying several different versions of DOTA, I found the clue in charlvz’s code (thanks charlvz). I was following the advice of the demo code documentation and trying to load the .wpb.dwl file, not the .dwl file. Strangely I can successfully download a .wpb.dwl file of 87600 bytes but not one of 90565 bytes. Loading the .dwl file works - as the ADL documentation suggests. 
Thank you all very much for your input and help.
