APN will recover when mangOH Yellow reboot

mangOH Yellow

Hi,

I use microcom /dev/ttyAT to change APN, but it always recover to “iot.swir” when reboot.

Any idea for this ?

Thanks,
Albert

you can change profile ID 2
e.g. at+cgdcont=2,“IP”,“APN”

Hi jyijyi,

Thank you for your reply.
I know that “at+cgdcont” can set more APN, but I use mangOH red with WP7702, the APN didn’t recover to “iot.swir” when reboot…

How can I freeze the first APN on mangOH yellow?

Thanks,
Albert

what is the return of the following?
AT!UIMS?

then it should use the physical sim card slot.
What kind of SIM card are you using?
How about download the clean official FW to it?

Hi jyijyi,

Because I use mangOH yellow with Octave, my firmware was that download this url:
https://docs.octave.dev/docs/getting-started-with-the-mangoh-yellow

and

https://downloads.sierrawireless.com/mangOH/spk/yellow_wp77xx_0.6.0-octave.spk

I use the USIM when connect internet.

8

maybe the sierra USIM has set the APN, have you tried with other normal sim card?

9

Yes, I use other USIM to test that have same status…

10

then it means the image you download will change the APN automatically, but the offical WP77 image will not, is that what you mean?
Have you tried download the official WP77 image to it to confirm?
Have you tried to download the octave image to mangoh Red board with WP77 and see if it will change the APN?

is that only the yellow_wp77xx_0.6.0-octave.spk image will make the problem but no problem is found for mangOH-2.1.4.wp77xx.spk (mangOH Red image)?

11

If you are using Windows 10, be aware that it may configure the APN if it is permitted to manage the connection.

12

seems this is caused by clouldInterface application:

root@swi-mdm9x28-wp:~# cm data
Index: 1
APN: iot.swir
PDP Type: IPV4V6
Connected: no
root@swi-mdm9x28-wp:~#
root@swi-mdm9x28-wp:~# cm data apn hkcsl
root@swi-mdm9x28-wp:~#
root@swi-mdm9x28-wp:~# app start cloudInterface
root@swi-mdm9x28-wp:~#
root@swi-mdm9x28-wp:~# cm data
Index: 1
APN: iot.swir
PDP Type: IPV4V6
Connected: no

13

You are right. But this APP will auto start on yellow spk. Can I custom this version framework?

14

why don’t you write a script to add AT+CGDCONT after boot up?
This is the easiest way.

15

Yes, I use this way on EVT, but we need to use with product…Can I custom this on Legato?
We will send data to Octave with WP7702.

16

Hi shib,

Yes, I have notice this status on Windows 10…
So, I always demo mangOH yellow with Linux on customer side.

thanks,
Albert
