To send manually AT commands to the module, as shown in the next paragraph, you may use the serial
terminal emulation minicom. To install terminal emulation use the following command:
sudo apt-get install minicom<enter>
Assume that the module is using the default #PORTCFG=0 configuration. Enter one of the following
commands to use USB0 or USB3 port of the module, refer to Tab. 2.
sudo minicom
–
D /dev/ttyACM0<enter>
sudo minicom
–
D /dev/ttyACM3<enter>
6.2 NCM Activation on the Module
Assume that the module is using the default #PORTCFG=0 configuration, and the default #USBCFG=0
mode. Execute the following steps:
•
USB cable is already plugged in, see previous chapter.
•
Run the minicom serial terminal emulation connected to the USB0 port of the module
(/dev/ttyACM0 on Ubuntu side), see previous chapter.
•
Enter the AT#PORTCFG=? Test command. If the entered command is not echoed, enter the ATE1
command to enable the echo.
Test command returns, for each Variant value, a short description on the logical connection regarding
physical serial ports/USBx ports and access points (AT parser instances, Trace), see below:
AT#PORTCFG=?
#PORTCFG: Variant=0: AT= USIF0 USB0 USB3; STT(Trace)= USB1
#PORTCFG: Variant=1: not supported by this product
#PORTCFG: Variant=2: not supported by this product
#PORTCFG: Variant=3: not supported by this product
#PORTCFG: Variant=4: not supported by this product
#PORTCFG: Variant=5: not supported by this product
#PORTCFG: Variant=6: not supported by this product
#PORTCFG: Variant=7: not supported by this product
#PORTCFG: Variant=8: AT= USB0 USB3 USB4; STT(Trace)= USB1
