The Software Integration and Development Guide states that the driver should contain the source code, the binaries and the instructions on a readme.txt file, however I can only find the binaries. Do you know where I can find the instructions and the source code?
This modem is a bastard. It looks like an Intel modem with a Sierra label,. And it is only ever sold as part of laptops. It has never been available in the embedded - small system integrator - market. Support is provided exclusively by the laptop vendors using the modem.
You can obviously not use any Qualcomm specific drivers or software like MBPL with this modem… It is based on an Intel XMM7160 chipset.
The default configuration is MBIM, and it will work with the cdc_mbim driver and associated userspace tools like ModemManager etc.
The band B3 is used, and it is supported by the EM7455.
How can I find why my sim is not registering to the network? It’s working well when I use it with my smartphone.
Maybe the signal strength is not high enough for the antennas of the modem. I’ll try in another location in a few days
