This is the built-in 3G/4G modem in a Fujitsu Lifebook laptop. I’m told they should be the same as the MC series.
The Extended AT Commands document lists some AT!STK… commands;
AT!STKVER does display a version number, but the rest just seem to give ERROR:
Any ideas what I’m missing, or where I’m going wrong?
It doesn’t help that the documentation is pretty opaque;
eg, it talks about “unsolicited SIM commands”, but the 3GPP specs say that the SIM can’t do anything unsolicited. I presume they mean “unsolicited” in terms of the host-ME interface, rather than actually unsolicited from the SIM itself?
Even with that, it seems that they sometimes get “command” and “response” muddled-up…?
You might want to check out the current QMI code in oFono, libqmi and the CodeAurora Gobi project and see if there is some STK example code there. But I wouldn’t be surprised if you’re on your own here… All these projects have naturally focused most on making basic services work, and STK is rarely requested.
