EHS6T-USB: What is the function of every /dev/ttyACMx? | Thales IoT Developer Community


March 9, 2017 - 10:16am, 2386 views

Hi friends,

I have tried to find a thread about this question, but I have not got nothing. I have also checked the documents:

  • BGS5 AT command Set.pdf
  • ehsxt_bgsxt_hd_v04.pdf.

...without success.

I have worked with Quectel´s UC20, it has 4 usb ports:

* ttyUSB0 --> DM (Diagnose port, used for FWupgrade and catching log)

* ttyUSB1 --> GPS NMEA out

* ttyUSB2 --> AT commands

* ttyUSB3 --> PPP or AT commands

The EHS6T-USB offers 6 /dev/ttyACMx, but it looks like the 6 ports had the same function.

Every ttyACMx has a functionality or the 6 ports has the same function?

Thanks in advice.

Best regards.
