HL8548-G FOTA firmware update problem

IoT Modules Legacy HL Series
1

Hi everybody,

I’m facing a problem during the HL8548-G FOTA firmware update.
I have modem which were originally in version 5.5.22. I would like to update them to the latest version (5.5.25) though FOTA.
I’m not able to update them to another version through FOTA. The modem look like to reboot indefinitely instead of downloading a new firmware. I tried to downgrade or upgrade it but the problem is the same for both cases.

I used the “RHL85xx.5.5.14.0.201502091756.x6250_1.exe” oneclick updater to downgrade one modem to an old version. After that I was able to update that modem from the old version to the latest version (5.5.25).

Here is my log:

+WDSI: 18,“98%”
+WDSI: 18,“99%”
+WDSI: 18,“100%”

Do you know what the message after +WDSI: 14 means?

Here is the Airvantage status:

FOTA Annotation 2020-09-01 113852
FOTA Annotation 2020-09-01 113852799×459 32.4 KB

Here are the test I made:

V5.5.14 > V5.5.25 : OK
V5.5.16 > V5.5.25 : OK
V5.5.18 > V5.5.25 : OK
V5.5.22 > V5.5.25 : ERROR
V5.5.23 > V5.5.25 : ERROR
V5.5.24.2 > V5.5.25 : OK

Is there a bug in the 5.5.22 and 5.5.23 FOTA update service?

Best regards,

Hi,

I’m trying to add more information to my previous problem but now I’m not able to synchronize my module to AirVantage. When I try to synchronize, I receive the +WDSI: 7 error but not with all version of firmware.
Here are my logs when OK:

AT+CGSN

359516050776741

OK
AT+KGSN=3

+KGSN: HE748602510810

OK

OK
AT+WDSS=1,1

OK

+WDSI: 4

+WDSI: 6

+WDSI: 8

AT+WDSE

+WDSE: 200

OK

So I updated it through the FOTA to the 5.5.25 version and I tried to synchronize it again.
And here when not OK:

AT+CGSN

359516050776741

OK
AT+KGSN=3

+KGSN: HE748602510810

OK
AT+WDSS=1,1

OK

+WDSI: 4

+WDSI: 6

+WDSI: 7

AT+WDSE

+WDSE: 500

OK

The last server HTTP response is “500” which means “Internal server error” so the problem seems to come from the AirVantage server.

you can try delete the module in Airvantage server and register again.

Hi jyijyi,

Thanks for quick reply.
I already tried that solution but the problem persists.

Here says you can check +WDSG:

I would like to add that this module was working fine on AirVantage 2 weeks ago.

8

does this happen to one module only?

9

No, I have a second module with the same symptom. These modules are with old hardware (HL8548-G downgrade firmware).

10

I just tested a recend module in version 5.5.25 and I was able to synchronize, change the firmware to the previous version through FOTA and re-synchronize without any problem.

11

Does anybody have an idea about that problem?
