Hi Sound,

Please download the latest legato 20.08.0, firmware SWI9X15Y_07.14.01.00 version and retry.
Did you install any application on wp7502? If yes, try to remove it.

my version frimware.
Firmware Version: SWI9X15Y_07.14.01.00 595652d jenkins 2018/10/26 08:34:29

Software on the module is a script that starts a radio channel.
The bottom line is that the same module with the same software is on another object.
And everything is fine with him

Hi sound,

This issue has not been reproduced on WP7502 legato 20.08.0, firmware SWI9X15Y_07.14.01.00 on my side.

Can you share with me the script you run?
Do you still face an issue reboot the modem after switching it to AUTOMATIC mode?

What kind of commands do you do that will lead to the disappearance of the radio interface? Is it another issue?

Hi sound

Please share source code, scripts as attachments.

Can you share with me the log file what you want to do step by step i.e. 1, 2, 3, etc …, and say where the issue is?

Do you still face an issue reboot the modem after switching it to AUTOMATIC mode?
Is it another issue?

sound · November 26, 2020, 11:13am

Yes. I am facing this problem.
This problem is repeated.
usually at night. at 3-4 hours.
A reboot is in progress. and then the radio channel disappears. it does not rise anymore. therefore, I do not have access to the log.

in the office, the radio channel disappeared. I connected via internet and received a log file.
I showed it above.

upload file write
Sorry, new users can not upload attachments.

Hi sound

Can you send source code, script files to me by mail or FTP server (example https://wetransfer.com/) ?
What do you want to do step by step i.e. 1, 2, 3, etc …?
So I can give it a try.
