FX30s LTE - Registration state to cellular network changes every 60 minutes

eddie435 · May 10, 2019, 7:14pm

Hi all,

I’m testing my app on the FX30s LTE model. I’m not having any problems with my app so far, but I’m noticing that the registration state of the modem is changing consistently as follows:

> registered state = home (for one hour),
> registered state = searching/none (for half an hour),
> registered state = home (for one hour),
> registered state = searching /none (for half an hour)....and so on.

I think the problem might be associated with the AirVantage Connector api, but I’m not sure.

Has anyone seen this behavior?

I stopped my app but it didn’t make any difference. See log below:

Thanks.

Regards,

Eddie

@eddie435,

Not sure which FX30 you are using since you say to are using the LTE version, there isn’t an LTE version other than the LPWA one, otherwise you are looking at the standard 3G version?

Re the registration state do you see it attaching and detaching from the network through AT commands? To check this I would enable the unsolicited responses as below and leave it to run, ideally with a terminal that has time stamps on it.

at+creg=1
at+cgreg=1

This will show if it is coming on and off the network, if it is then it will almost certainly not have anything to do with the connector as it will leave the signalling firmware to do its thing and select the best network.

Regards

Matt

I’m not sure, but could this be a bug in the firmware? Currently I’m testing with a T-Mobile account. I will try with a AT&T account to see if there is any difference.

Thanks!

Hi Eddie,
Did you experience the issue on AT&T as well?

Could you explain how to started your data session please?

BR,
Chris

eddie435 · June 3, 2019, 1:20am

Hey Chris,

I didn’t experience the same thing with AT&T.

I found that with T-Mobile, when I changed the cm radio rat AUTO to GSM, it stop giving me the problem with disconnecting every hour. I don’t know why, but the T-Mobile account I have will not connect to LTE. Connecting to GSM is no problem. Any thoughts?

Thanks!

Eddie

cchenry · June 4, 2019, 4:10pm

Hi Eddie,
I wonder if there is a T-mobile specific configuration setting within the carrier cfg. Could you try for testing purposes, installing the T-mobile SPK file from here:
https://source.sierrawireless.com/~/media/support_downloads/airprime/software/wp77xx/release9.1/9999999_9907618_swi9x06y_02.13.02.00_00_generic_001.009_000.ashx?la=en

Be aware, the T-mobile image is released for the standalone WP77xx module, and hasn’t been officially released for the FX30 product line.

BR,
Chris

Chris,

I uploaded the file as you suggested, but it made no difference. I still wasn’t able to set the RAT to LTE for my T-Mobile account, only GSM.

Others I have tested successfully are AT&T and Verizon.

Hi Eddie,
Could you please confirm which SELRAT and bands you’re trying to enable?

Please see the supported bands:

I believe TMobile has an NB1 network but could you please verify your coverage?

BR,
Chris
