errno 128 is either KEYREVOKED or -1 EPERM.  Any idea why this is failing?

Hey,

have you provisioned the certificates for AWS on the modem?

[brendanyounger]

Yes, I can successfully connect directly to my AWS IOT broker.  This error is occurring when downloading firmware from an unsecured HTTP server.  As you can see from the Range: header, about half of it has been downloaded before I get this error.

Any ideas about what is causing the error?

 Does it always happen at the same point during download, or is it random?

[brendanyounger]

I have confirmed that the download works fine with a Verizon SIM.  The issue appears to be related to some of the roaming MVNO SIMs I have been using.

We do need to be able to run on these roaming SIMs like Hologram and Twilio, though.  We are seeing issues with low data rates, hung downloads, and an inability to send/receive SMSes.

Could it be a connection issue? You can check the signal strength with the AT%XMONITOR command. Make sure you have a stable connection before attempting FOTA.

aws_fota program is unstable. I succeeded in updating a program once but failed many times. I don't get err 128, but get "aws_fota_mqtt_evt_handler: Failed! -14." I'm using Hologram SIM in Japan.
