Hi
If you are using DWLWIN once the download is complete, reset is performed automatically whereas if you are downloading through wdwl its advicable to perform a soft reset.
ati is showing error that means firmware is not downloaded correctly(i guess other commands are also giving error in your case).Try doenloading the firmware again.

Actually, I think it is essential that you perform a soft reset!

AT+WDWL effectively puts the device into “download mode” - and it will stay in that mode until you issue AT+CFUN=1
