FTP using gemalto Cinterion ELS31-V with V 4.3.3.0 36343 FW in it | Thales IoT Developer Community

April 18, 2019 - 10:03pm, 1803 views

We have been testing the use of this ****m for a bit. However several quirks are bothersome with it.

The biggest nusance however is it doesn't give URC responses from the FTP server. This hangs the FW on the device driving, and we have to power cycle the unit some***** 4 or more ***** before URCs are received.

So here is a log of what is going on at about 2019-04-18 14:41:09.458 we issue the FTP command with NO response. We set URC setting for FTP 2 *****  (it doesn't make a difference as we were doing it once before and had the identical results). The the connection then MUST be closed (AT^SISC) and the ****m power cycled (AT^SMSO) then powered off then powered on. Now I know the unit is logged into the server. Because I get 0 length files when this happens on the FTP server. So it DID log in, however I CAN'T tell, because of NO URC's being returned, even though they seem to be explicitely requested.

Suggestions very welcome
