Hello @bb27

as long as no certificate has been downloaded AT+CSETCA? will return an error - that happens for me too.

According to the documentation there is no AT+CSETCA=? (e.g. test) command - so I’d expect an ERROR response.

I am not aware of any specific precondition. Maybe with the exception that it might help to reboot the modem after every failed try to download to have a clean start.

Sorry, at this point in time I am out of ideas.

Thanks
Felix
