AT+WOPEN=3 -> ERROR, since upgrade from R71 to R73 !

IoT Gateways Legacy FX/FXT series

Hi,

After following the procedure provided by my supplier (which went smooth), my modem now returns ERROR every time I use the at+wopen=3 command.

Is it a known problem ? Is there a fix ?

Regards

1/ Put the modem speed to 115200 bps: AT + IPR = 115200; & W
2/ Send AT + WDWL and load the file using HyperTerminal dwl.dwl (send a file via XMODEM 1K)
3/ Once the file is loaded, reset the module by AT + CFUN = 1
4/ Send AT + WDWL and load the firmware 7.3 R73_00_full_fsu002.dwl (always XMODEM 1K)
5/ Once the file is loaded, reset the module by AT + CFUN = 1
6/ Send AT + WDWL and load the file w.dwl (always XMODEM 1K)
7/ Once the file is loaded, reset the module by AT + CFUN = 1
8/ Check the loading ATI3

Hi,

Event if the modem returns an error, the flash memory is cleared.

This unexpecting error is fixed since the R73a firmware release.
