Hi all,
I am trying update my midlet from our webserver using EHS6 GPRS Terminal. We get an error message [OTAP] ERROR: Server not found. This method works on our old TC65 Terminal but not on this.Using hyper terminal I do the following:
AT^SJOTAP=,http://dev.gasdata.net/****/RS232Demo.jad,a:,,,gprs,general.t-mobile.uk,...
AT^SJOTAP
AT^SCFG="Trace/Syslog/OTAP","1"
Response back:
OTAP.OUT STARTED
[OTAP] ERROR: Server not found.
[OTAP] Transfer finished.
[OTAP] DONE with status: JAD Server Not Found
[OTAP] operation failed
[OTAP] Reboot now.
Any help would be appreciated. Thanks.
Hello Bartłomiej,
i have the same problem.
- Can you send me the firmware as well?
- Is it possible to update this firmware over the air?
Regards
Andreas
Hello,
Please send me what module you are using (ATI1 reply).
To update the firmware over the air you would have to prepare the application that would do that and put the firmware on some http server to be downloaded.
Here's the example for remote firmware update: https://iot-developer.thalesgroup.com/showcase/fota-example-firmware-upd...

Hello Andreas,
You should have got the email.

I have ARN49. But, I do see that "OTAP" is not very stable. Most of the time, it works. But once a while, it failed with "JAD Server Not Found" although the server was fine ( I was able to access the server via browser) Any idea how to debug it?

Hello,
Could you state (if possible) how frequently it happens? Maybe it has something to do with the cellular network coverage or quality at that particular moment or backbone network. Does it depend on the module location?
You are unable to trace on the module. You could make some TCP trace on the server if you have access to it but there might be nothing to trace as the debug information was "server not found".
Does the server have the correct MIME settings (content-type):
* for JAD files it should be "Content-Type: text/vnd.sun.j2me.app-descriptor"
* for JAR files it should be "Content-Type: application/java-archive"?

It happens very often in my setup. The command always fails if it is called twice within 1 minute. it is not consistently successfully although 5 minutes is waited between 2 OTAP calls.
As far as the signal, I think it is good since "at+csq" returns 14.99.
Also, we checked. our server does have the correct MIME settings.
Any more idea? Thanks!
Hello,
The network seems fine according to CSQ and previous SMONI. But have you tried to test in different locations or with different providers? Maybe it is somehow network related.

Dear Bartomiej,
recently I got the same problems with OTAP, which fails to connect to the internet if not previously preset by SJNET command properly.
It is related to all BGS5T terminals running the firmware REVISION 01.100 A-REVISION 00.000.10
I would appreciate to get the newer firmware in order to fix this issue with our modems in stock.
Thank you very much in advance!
