Digi Embedded Yocto includes support for the following cellular modems:
When you are using ModemManager, the initialization of some cellular modems could fail if there is no power cycling of the card between two initializations. This could happen during a software reset. To avoid this situation, we recommend you incorporate a mechanism in your carrier board to power cycle the modem at boot time.
The cellular support in Digi Embedded Yocto is based on the NetworkManager and ModemManager open source software packages.
