…except for AT which returns OK.
Hello,
I have the modem connected via USB and all seems fine. The light is flashing at the speed to show it has registered with network and is idle.
Connections using an SMS program and just PUTTY always get the same result. Every valid command returns ERROR except for AT.
I just want to use as a stand alone device.
Am I missing some thing?
Thank you for your help.
Paul.
Hi Paul,
How about below commands?
AT+WDWL?If not getting ERROR, the FW inside FXT009 may not boot properly.
Try re-download FW may recover it.
FW is available below:
http://developer.sierrawireless.com/Resources/Resources/AirPrime/Software/Firmware%20package%207,-d-,52.aspx
Refer to release doc for download procedure if needed
http://developer.sierrawireless.com/Resources/Resources/AirPrime/Software/Release_notes/Firmware_7_52.aspx
Hope it helps.
Thank you for your reply lotam, the command also returned ERROR.
I will update the firmware on both of the FXT009 modems I have now, and see how that goes.
Regards
Hello,
I had trouble upgrading the firmware on one of the modems. I uploaded the dwl.dwl file and started uploading the R7.52.0_fxt009.dwl file and I kept receiving a message similar to “modem cleared connection” using ClearTerminal. Admittedly I was connected via a USB cable.
My modem now seems to do nothing the red light is permanently on and I can not connect to the modem with USB and only serial, yet all commands again now only respond with error again.
Is there a way I can fix this, sorry to be a pain. Also I had two entries under Modems in computer management, there is now only one LSI HDA Modem
Paul.
Hi Paul,
Are you sending “AT+CFUN=1” after uploaded dwl.dwl?
Can you try using UART for FW upgrade?
If it doesn’t work, maybe we have to try DwlWin…
Thx
Updating firmware causes the unit to reboot. When the unit reboots, it restarts the USB - which the PC will see as the unit being unplugged, and then plugged back in again. Many PC apps do not cope well with this…
Hence the suggestion from lotam to use the UART instead…
Hi Guys,
Yes Lotam, I was executing the following commands:-
at+wopen=0
at+wdwl
at+cfun=1
at+wopen=1
but each command just returns “ERROR”. This is the same when using UART. It seems the only commands that return a response are:-
at (OK) and ati3 (LSI SoftModem Version 2.2.100)
also whenever I run a “query modem” from the modem properties diagnostics tab in windows, those queries work too.
I understand what you mean awneil as I could see this happening but made a silly assumption that it would be ok. Is there a way to force a reset on the device?
Regards,
Paul.
Hi Paul,
Obviously the modem port whereas you are getting “LSI SoftModem Version 2.2.100” is not FXT009 but the built-in modem on your PC.
Can you check the port assignment via Device Manager?
Thx
Hi Lotam,
You are 100% correct, I had failed to notice what I was doing and assumed a connection to FXT009.
I have since connected and successfully upgraded the firmware now on the first mode.
I moved on to the second modem, but ran in to a similar issue where it receives an error when downloading the file R7.52.0_fxt009.dwl have successfully downloaded dwl.dwl and reset the module with UART.
It always stops at the exact same point 958kBytes - “Cancelled by receiver”. I can execute certain commands AT(OK), ATI3(R7.43.3.201306260837.FXT009 1713240 062613 08:37)
AT+WOPEN=0 returns an error. I have noticed something different but don’t think it is a problem but whenever I reset this module, it will POST:-
at+cfun=1
OK
+WIND: 13
+WIND: 1
+WIND: 16
+WIND: 4
+WIND: 10,“SM”,0,“ON”,0,“EN”,0
+WIND: 11,“FECA527AAC927BEFBCB861C6865816B3”,
I have tried various protocols, XModem-1K, XModem and different flow control. Admittedly I know very little about these.
Hope you can offer some further assistance.
Regards,
Paul.
I have managed to get it to work. Very strange, by cancelling a download of the R7.52.0_fxt009.dwl file and then downloading the dwl.dwl file and then the R7.52.0_fxt009.dwl it manages to download the whole file and resets fine with new firmware:-
ati3
R7.43.3.201306260837.FXT009 1713240 062613 08:37
*** ERROR IN DECOMPRESSION ***
*** ERROR ***
*** UNRECOGNIZED FILE ***
at+wdwl=1 at+cfun=1
+WDWL: 0
---------at+cfun=1 at+wdwl
+WDWL: 0
---------at+cfun=1
OK
ati3
R7.52.0.201306260837.FXT009 673436 062613 08:37
OK
