Which source is true? :-) Or > it's just a wrong text on that BGA? I think it is simply the fact that (at least) for the Linux on the Cortex-A5 it doesn't make any difference whether it's running on a 9615 or a 9215. The difference is presumably primarily in the cellular radio interface and possibly DSP capacity? From the few publicly available information the 9615 adds Ev-DO (3GPP2) capability, while the 9215 is GSM/UMTS/LTE (3GPP) only? btw: I just created a new mailing list for any future public discussion on the Qualcomm Linux based cellular modems, see qc-linux-modems at lists.osmocom.org and/or https://lists.osmocom.org/mailman/listinfo/qc-linux-modems -- - Harald Welte http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

See https://www.qualcomm.com/media/documents/files/gobi-product-specs.pdf The 9200 is 3GPP-only and 9600 adds 3GPP2/EVDO, both without voice. The 9215 and 9615 are the voice-enabled versins of both. -- - Harald Welte http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Maybe some blocks are going to be same, but who knows. I should probably download finaly the kernel sources and look around to find this question myself :-) > The difference is presumably primarily in the cellular radio interface > and possibly DSP capacity?

I have just added some information to our wiki at https://osmocom.org/projects/quectel-modems/wiki/Huawei_ME906v and https://osmocom.org/projects/quectel-modems/wiki/Huawei_ME906v_adb Summary: * they don't really use the Linux for anything. Not even QCMAP_ConenctionManager running * not many HUAWEI modifications recognizable on the Linux side * no fancy FOTA updates or AT+QLINUXCMD equivalents * DIAG is present by default * ADB can be enabled, but requires serial console soldering at least once :/ Would be nice to find a way to enable adb without having to solder. I'm still working with Huawei to release the related complete and corresponding source code under the GPL.

While looking around, I somehow managed to get my device stuck in QDL mode where I have only one ttyUSB available and lsusb shows the device in QDL Mode. I have the flashing utility but I don't have an image at hand. Could anyone send it to me or let me know where I can get it? While searching I saw ftp://ftp2.quectel.com but that has the kernel source rather than what I'm looking for, Thanks.
