EHS6T-USB unusable after firmware update failure | Telit Cinterion IoT Developer Community

October 19, 2017 - 3:53pm, 2840 views


We were updating the firmware by means of the tool given in "ehsx_rev03.001_arn0000051" (the complete name of the executable is "ehsx_gwinswup_rev03.001_arn0000051.exe").  We used ASC0 at 115200 .

We got success in a couple EHS6T-USBs.

But one of our EHS6T-USBs got a failure in the updating proccess and now it's unusable.

*It's doesn't repond to ASC0 AT cmds

*When I connect an USB cable, I can't see the "Cinterion EHx USB Com PortX (COMXX)" list in the Windows Device Manager (section Ports (COM and LTP) ) .   So is not possible to send at commands by USB
