EM9191 AT Commands


We are using EM9191 module, connected with our CPU at PCIe interface.
Please let us know, what is the requirement to run AT commands from CPU.

  1. Do we need to use any GPIO or other interface other than PCIe ?
  2. Do we need any driver at our CPU for AT commands ?


Hi @himgupta ,
In order for the EM9191 module to be able to run AT commands with your host via the PCIe interface, the first thing you have to do is install the PCIe driver for it.
Please email tech support: support@sierrawireless.com to get PICe driver for EM9191 module and be guided on how to install it.



Re contacting support, I would go through your commercial channel i.e. where you bought the unit from.
