Serial communication with Sierra Wireless EM9291
-
Hi,
I am using a Sierra Wireless EM9291 modem with VOXL 2 and the carrier board, which I want to connect to over serial to send AT commands.
I cannot find the device path in /dev, ls /dev/ttyUSB* returns no such file or directory. How should I communicate with the modem?

@schew, hello, have you tried setting up our standard software using
voxl-configure-modem
, following this documentation page https://docs.modalai.com/5G-Modem-user-guide/ ? That would be a good first test. -
@schew Why do you need to send AT commands to the modem? What are you trying to do with the AT commands?

I have configured the standard software with voxl-configure-modem; it works and I can connect to the internet, however the APN is different as I am not based in the US.
I am planning to use the AT commands to configure some of the more specific parameters of the modem e.g. setting bands, etc. -
@schew There are some scripts in our
voxl-modem
repo that use AT commands. https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-modem/-/tree/master/scripts?ref_type=heads
