Q2687: cannot upload the application via M2M


#1

Hi, all

When I download my application to Wireless CPU (Q2687) via M2M, it is not successful.
For example:
at+wdwl
+WDWL: 0
*** MEMORY ALLOCATION ERROR ***
*** ERROR ***

I have check the R&D storage size
at+wopen=6
+WOPEN: 6,1024,4096

Whether The Sierra wireless disable the funcaiton or not. Does anybody tell me what is the matter?

Hi,
you could try reinstalling the firmware (dwlwin).

How big is your firmware?
We had that error when loading large files.
You can try to re-size with AT+WOPEN=6,512 for example and then try again.

I’ve just been getting the same error when trying to update the firmware on a WMP100 from M2MStudio.

AT+WOPEN=3 made no difference;
AT+WOPEN=6,1024 made no difference;
AT+WOPEN=4 finally got it working. :confused:
