Hi Stefan, You’re too fast for me 😉 Developer Studio 2.1.1 main updates: - Target management has been improved with OS Awareness. This is bringing much more visibility to Open AT application execution with some insight on Task status, Stack status and peak consumption, and Heap size and current usage. - The ability to Record & Replay on UART which was existing on legacy TMT is now available as well with Developer Studio. - USB Robustness has been improved, thanks to a revamp of the USB driver. - JTAG configuration for some WMP customers has been improved, to ease its usage with Segger probe. - Conditionnal Breakpoints with embedded debugging which was already available, is now fully validated. Download [Developer Studio now](http://developer.sierrawireless.com/en/Resources/Resources/Software/AirPrime%20Open%20AT%20Framework.aspx) and get latest [release notes](http://www.sierrawireless.com/Support/AirPrime/releasenotes/Developer_Studio_2_1_1.aspx).

How to prevent DS from reading “target information” from the device whilst trying to upload files? That information is never readable on my FXT009’s, previous DS disregarded that and did upload, and this one gets stuck. ---

Please have a look and check if it helps. I downloaded the 3.8.2 driver but it made no difference, opening a port still hangs up at the stage “Load model element: Target Informations”. I also tried it with our application off (WOPEN=0), and again with our application removed (WOPEN=4), with the same results. Attached is a screen shot showing the results of trying to open the port. ![](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/d/d22bedcec0883640e4d600255426106a67734467.jpg) ---

We’ve tested this now with 4 different modems, 2 FXT009 and 2 FXT 003, all running FW ver 7.46 and bootloader ver V08b11. One of the 4, an FXT003, can be opened from DS 2.1.1 every time we try it, none of the other 3 can. The key difference we see is the three that don’t work show up in device manager under the modems group, and the one that works shows up in the ports group. In the devices tab in DS, the 3 that don’t work have type USB (Modem), while the one that does has type USB (COM). Also the 3 that don’t work don’t work if you try to connect by the serial port either. The one that works can be successfully opened using either the serial port or the USB port. 3 of the 4 modems including the one that works are brand new out of the box. ---

On the targets which are not connecting, please can you: - clear the console content - request a refresh in the target status view - copy-paste the console content here? We can see a “+CME ERROR: 3” result in your console log, please can you check if there is a difference in AT+CMEE configuration between your 3 non-working targets, and the working one? ---

We’ve managed to get all 4 modems working now. There were a few issues causing the difficulties: - The new USB driver didn’t install with the upgrade to v2.1.1 (not sure if it’s supposed to or if it always required a separate installation) - A couple of the modems had AT+CMEE set to 1 - opening the port times out if CMEE is 1, which I suspect is new behaviour with 2.1.1 (at least we’ve never noticed it before) - One of the modems had a firmware version of 7.43, where a minimum of 7.45 seems to be required for the new driver. I had assumed the modems were all running 7.46 as they came in the same shipment. ---

Good news! > [@](#): > > - The new USB driver didn’t install with the upgrade to v2.1.1 (not sure if it’s supposed to or if it always required a separate installation) The USB driver indeed requires a separated (and manual) installation/update. We’re studying the possibility to have a notification mechanism also for the USB driver updates… > [@](#): > > - A couple of the modems had AT+CMEE set to 1 - opening the port times out if CMEE is 1, which I suspect is new behaviour with 2.1.1 (at least we’ve never noticed it before) Can you remember which FW version is running when you get troubles while +CMEE=1 is active? From what we’ve tested, connection seems always successful with +CMEE=1 and FW version 7.46, but we could get trouble with former versions. > [@](#): > > - One of the modems had a firmware version of 7.43, where a minimum of 7.45 seems to be required for the new driver. Indeed, the command used to switch USB mode (AT+WUSB) requires FW 7.45 or higher. ---
