Lenoveo-branded EM7455 AT Mode

IoT Modules MC/EM Series

Hi,

for an embedded project, I’m trying to connect via the AT port to the Internet. Unfortunately, I bought a Lenovo-branded EM7455 card, which does not power up unless FCC Auth is given. I know this can be sent using QMI, but is there a way to achieve the same effect using the AT port only?

Thank you,
Andreas

No. You can send it with embedded QMI over MBIM. Using the ttyUSB to connect (via ppp) is not efficient. Just use MBIM or QMI.
