EM919x host interface type

IoT Modules MC/EM Series

Hi,
I am using the EM9191 in my product.
I would like to know if there is an option to select the host interface type in the AT commands.
Thank you,

do you mean the setting in AT!USBCOMP?

Hi,

I understand that the default host interface in the EM9191 is PCI.
I would like to change it to USB.

Can you please let me know if I will still have USB to COM port functionality when the default host interface is configured to PCI?

Thank you,
Roei

Hi,

Then we can’t do it through the AT!USBCOMP? command.
It must be done by hardware.

Thank you,
Roei
