FOTA for FX30S how to

#1

We are moving into finalizing this product and there is some points we still need to finalise, one is the firmware update over the air (FOTA).
This is a new concept developed from Sierra Wireless and even if I have been looking for information I haven`t found what I needed:

  1. Is this FOTA performed through the AirVantage web page.
  2. Can I download any firmware (cwe) even if this is an image made from a legato system I have built.

Especially in regards to point (1), I have AirVantage app running in my target, with internet connection established through profile 2 (modemService), everything works as I am sending data from the target to our backend, but when logging into the AirVantage I can`t see my device, so my question is if I need to do anything specific to get this working? Or as long as the AirVantage app is running it should connect?

#2

  1. yes, FOTA is performed in https://eu.airvantage.net/
    You need to first register module in AVMS website and use AT+WDSS command to connect to server.

  2. I have tried to download custom legato CWE to WP76.
    This is the file I upload to the AVMS server.
    The revision inside bundle.app “LE=18.03.0,MCU=002.009” has to be met with the version after upgrade.

#3

would you know how this can be done through the legato interface?

#4

suggest you trying with AT command first to make sure everything is working fine.

you might also see the sample here:

#5

Air Vantage agent reported update status: AUTHENTICATION_STARTED
Air Vantage agent reported update status: AUTHENTICATION_FAILED
Air Vantage agent reported unexpected update status: 16
Air Vantage agent reported update status: SESSION_STOPPED

This is what I get when running those functions.

#6

if I use the AT command:
AT+WDSS=1,1
OK

but still the target doesn`t show as connected.

#7

you can enable the +WDSI indication:

at+wdsi?
+WDSI: 0

OK
at+wdsi=4479
OK

#9

you can delete the module in AVMS website and register again and retry and see if there is still problem.
BTW, are you registering for Fx30 module in the website?

#10

I have deleted and re-created the device in the AV devices, still same problem as before

#11

how do you register?

#12

Register → (add SN and IMEI) → Register (button)

#13

Are you registering for FX30 or WP77 module?]
Maybe you need to try both to see which one is working.

Did your application start “cm data” automatically?
If there is IP address in modem or IP address with !SCACT=1,1, the FOTA session cannot successfully established.

#14

I have registered the FX30S as this is the target I am using, can`t try all different combinations, so if you could be a bit more specific.

I am starting the modem from the legato framewrok, but I have noticed that running the avc session start will also kill my communication, so I wonder if this is also done inside the avc app.

#15

what is the meaning of “starting the modem from the leagto framework”?
You mean you establish the data connection in your app?

#16

“starting the modem from the leagto framework” means using of le_mdc interface to start the modem connection.

#17

as said before, you cannot do that for the test of AT+WDSS=1,1.
You need to shut down the application first to test the AVMS with AT command.

#18

If I trigger the AT+WDSS=1,1 then the it seems the modem will try to establish the connection (setup the data connectivity) but it will not work.
If I start the data connection manually (cm data connect) and after trigger the AT command, then the test is successful.

#19

Although it is different in my side, you have made it work then

#20

I need to get it working with the legato framework, so getting this working through the AT commands doesn`t help me .
