Etienne, I have done this on a unit and it seems to work on the USB interface (as per the attached) so I have no reason to suspect it does not work generally. Can you send the below? ati at+cgmr If the ATI response comes back with APPx (if you are doing this on the UART then APP3 is the default) then it means that it is the end point which is intended to be used for a data connection rather than anything else i.e. check network connection, sending SMS, etc. You will need to use the at!mapuart command on the USB port to re map it to the full AT command parser as these units only have one. Note if the full AT parser is on the USB port and you remap it to the UART the USB will have the end point enumerate but will not respond to AT commands, you would need to use the UART to switch it back. Regards Matt ---

Etienne, I presume that this is in the UART or USB? Assuming it is on the UART you need to get access to the USB AT command port which does not respond to the ATI command with an APPx and send the following command to it at!entercnd=“A710” at!mapuart=1 at!reset After this the full AT parser will be assigned to the UART and not the USB. Regards Matt ---

I found out that ttyUSB3 was responding something else to the ATI command (it was the only one actually) and sent him the commands you gave me. It deleted ttyUSB4 (which I was using so far) and created a ttyUSB5 with exactly the same behaviour and ttyUSB3 not responding anymore to AT commands. So i rebooted, hoping to reset the card, and now I found my ttyUSB4 again with exactly the same behaviour as before (no sms, etc), and ttyUSB3 still not really responding. Now i can reset and execute all 3 commands you gave me before on ttyUSB4, but nothing more. What could I do now ? ---

What is your end game? What interface do you want to use? Are you doing anything with UART or only USB end points? I have asked if you are using UART several time before and you have not told me so I have had to make assumptions. Regards Matt ---

I want to send a sms through any interface which could do it and as so far I worked on 3G connection with the interface ttyUSB4, I tried sending my messages through this mountpoint (/dev/ttyUSB4). I’d say ttyUSB0/1/2/3/4 are USB interfaces. My vision is that they are be emulated by UART interface (ttyUSB0-\>4 emulated by COM connected card) ---

Etienne, On hte units each USB end point is associated with specific functionality, there is no way to know what this functionality is without connecting to it and asking. There is no way to produce a hard guide since the way they enumerate varies depends on user set options with in the unit. TYPICALLY SL8 and old directIP units will enumerate as follows. /dev/ttyUSB0 - HIP/CnS /dev/ttyUSB1 - Diagnostic Monitoring port /dev/ttyUSB2 - NMEA data /dev/ttyUSB3 - AT command /dev/ttyUSB4 - Modem port (limited AT command capability) If you disable the NMEA then 3 and 4 would become 2 and 3 respectively when it next re enumerated. It may well me that you have switched the AT parser to the UART. I would suggest you connect to each of the /dev/ttyUSB ports in turn with minicom and see what the response to ATI is, if one of them comes back with a load of unit information (i.e. firmware version) rather than APPx then this will be the interface you need to use for the SMS. If none of the interfaces come back with a load of unit information then I suspect you have switch the AT parser to the UART and you wll need to connect to this and send at!mapuart=7 to it to remap the AT parser back to USB, then reset the unit and go through each of the interfaces as I have just said. Hopefully that should sort you out. Regards Matt ---

Thnks for this response and your help, it’s much more clear now ! One last question though, how can I connect to the UART to set it back to USB mountpoint on ttyUSB3 ? ---

Connecting to a UART is a problem if this is in your hardware as opposed to a dev kit (is it your hardware)? Not sure how you get around this, I have had customer do this in the past, its why I was specifically asking about interfaces early on but had to try to answer you without this information hence my comments about assuming certain configs as sending commands blind to the unit can result in configs you cannot get out of if you set hardware interfaces up. There might be some tools around to reset this config just through the USB if you go back through your disti. Regards Matt ---

Etienne, The CREG response shows that the unit is not attached to a network so you are not going to be able to send any SMS’s. Not sure why this is but you will need to sort this out first of all. I would try the following ```auto at+cops=0 //Leave it for 20 seconds or so after receiving the OK back to give it a chance to attach at+cops=? //This will take a few minutes to complete to show you the networks it can see ``` Regards Matt ---
