Z3C - Cellular only not working after power loss?

[ksumann]

Hi everybody,

We have a Z3C here which got its initial configuration through the dashboard.

It was running on cellular only as we did a power cycle by pulling the plug and insert it back again.

The device does not connect anymore with cellular only.

Firmware is 17.10.4

Anyone else seen this?

Have you tried a factory reset? Have opened a support case?

[PhilipDAth]

That should work.

If you put the SIM into a phone does the data portion still work?

[ksumann]

A factory reset should not work. The docs say that the initial configuration cannot be done by cellular only.

I didn't open a support case yet because its not reproducible. So i wanted to ask if anyone else has seen that.

Cellular modem on Z3C can be buggy at times. Which cellular provider are you using? Are you doing static via cellular?

[ksumann]

Provider is German Telekom using dynamic IP.

Do you have some links about this buggyness?

[alemabrahao]

I suggest you to open a support case.

Hi,

Have you any news about your issue?

From my side I got quite same behavior.

For month, I used Cellular Fail over without issue, and since several weeks, SM car is not detected ( ICCID no read, nor MSISDN ( Appliance status/Uplinks).

I did a RMA, but it is the sale with new HW!!

In firmware 18.208 release notes, there a few points mentioning cellular connectivity
