Talking at FOSDEM 2014


Third time in a row, I’ll also be giving a talk at FOSDEM this year:
LTE in your Linux based system

The talk is an introduction to QMI and MBIM devices, how they are exposed by the Linux kernel, and how you can use them from the command line through libqmi, libmbim and ModemManager.

See you there!

  1. I arrived too late. The room was already full 😦

  2. It was a small room, yeah :/

  3. Hi aleksander,

    maybe not the best place to ask but could you tell me please how can i use pds commands in qmicli? i have a evalboard with an gps receiver. i can read the gps data with at commands and it would be great to do that with qmicli. thank you for your great work!!

  4. FYI, we have a libqmi mailing list 😉

    Anyway, the issue is that the PDS related commands are not implemented in qmicli yet. Not a huge thing to do, just not done. If you’re up to the task, I already developed the GPS support using libqmi in ModemManager, so you may want to check that 🙂

  5. Thank you very much! I will have a closer look at ModemManager. Today ive noticed that the SINR value is not displayed in an LTE network but i could see the SNR Value. Is that device specific? I thougt SINR is an calculated value?

  6. Ah ok ive got it. Its an evdo property only. Is there a chance to get the cqi value? I guess only the snr value is by far not enough for some datarate indicators.

  7. For LTE you can get S/N, RSSI, RSRQ and RSRP.

    BTW; you may want to check at this program I wrote using libqmi… 🙂

  8. Ah thank you! Works quiet well. Some options to log/write in file S/N, RSSI, RSRQ and RSRP would be cool!
