    W800 SDK ethernetif (LWIP, to be more precise):

    Same for W600:

    I think we can easily fix it, we could even allow ourselves to just call obk config API to get device name... full name, that one here:
    Screenshot of device name change form with the full name BK7231T_WB3S_WhiteStripWindows highlighted.
    Just call CFG_GetDeviceName() there, we don't support non-BK APPs anyway, and even if so, we could do a #define check. What do you think, @max4elektroda ?

    DHT11 works:

    Shure, fixing the name should be easily possible in this case.
    I always looked for the strange name when I forgot the DHCP address, but never thought of fixing it...

    apologies, I thought it weird I couldn't find in code search. I was transforming hyphen to underscore in my head. :/

    So it's done - see https://github.com/openshwprojects/OpenBK7231T_App/pull/1508
    I didn't set the hostname in sdk code, but in hal_wifi.
    Reason: in lwip code the config seems not yet read (at least CFG_GetDeviceName() will always return NULL).
    So I went the easy way and (re-)defined the hostname just before connecting in "connect_wifi_demo()".
    I also added my approach for an uart driver - only tested with my preliminary NEO-6M driver:

    Looks promising, but lacks a meaningful use until the clock changes are merged and other sources than NTP are possible.

    Seems acceptable. Merged, thank you.

    Btw I think we may don't need separate makefiles for W800 and W600 in App, or at least for the App-specific part, maybe we could just include sub-makefile from, let's say, WX00 dir from both of them.

    Just let me finish my "textarea startup command" PR first: https://github.com/openshwprojects/OpenBK7231T_App/pull/1506

    One additional information / finding:

    Old host name as expected:

    Maybe @divadiow you finally want to make use of the additional item sent with the W801?

    A GPS driver? Very interesting, altough we may need to put that in a separate topic....

    However, can you change the name of the define? The rule is that entries from drv_main should have ENABLE_DRIVER_ prefix, and you just used ENABLE_NEO6M only.

    It should have been ENABLE_DRIVER_NEO6M, but it looks like in the code uploaded I forgot the #ifdef at all.
    So it works even with the wrong define...

    But that will be fixed tomorrow, I will call it a day now.

    And yes, I will open a separate topic, this was just a teaser for now (but it's also working with Beken, I didn't get uart working on LN882H (yet?)).

    It's funny that they even included their GIT repository in the zip:
    Screenshot of the 7-Zip program with the w800_1.0.5.zip archive open and a list of files and folders visible.
    Toolchain is a separate archive (csky-abiv2-elf):
    Screenshot of WinRAR with the w800_1.0.5.zip archive open, showing files inside the archive.
    A file decompression program window showing the contents of an archive named w800.tgz.
    And there is only Tuya adapter, I can't see any W800 source code?

    Since uart is present, it should work, maybe I can update the PR to resolve the merge conflicts (it's exactly 100 commits behind).
    In the end it comes down to the point if the split between clock and NTP code is accepted.
    I mean, there might be situations where you simply don't know where you are, so GPS might help ;-), but I intend to use it as a network independent source of time and even latitude longitude for sunset/sunrise calculation.
    As long as you have GPS reception, no network is needed to do even challenging time based switching.
    But actually NTP is the only source of time.
    I would like NTP to be only one possible source to set the clock, allowing other sources, too.

    Actual code with NEO6M can be found here:

    will also work with @insmod _w800 branch.
    The RSSI shown looks better, but trying OTA always fails for me (after (long) restart, old version is present...)
    Version is attached, just in case you want to try ...

    As long as I use Chrome OTA usually works, so I included the "local clock" and NEO6M driver to @insmod _w800 branch so you might actually use the GPS data:
    The W800 image is build with (aditionally):

    Code: text Expand Select all Copy to clipboard
    #define ENABLE_CLOCK_DST                  1
#define ENABLE_CALENDAR_EVENTS            1
#define ENABLE_CLOCK_SUNRISE_SUNSET       1
#define ENABLE_DRIVER_NEO6M               1



    If you start the driver with "setclock" and/or "setlatlong" it will set the values accordingly if GPS is locked. For me in Germany it's (with some slight hiding of my home ;-))

    Code: text Expand Select all Copy to clipboard
    backlog startDriver NEO6M setclock setlatlong fakelat=4190.5  fakelong=01245 ; CLOCK_setDST 0 3 1 2 60 0 10 1 3 0; clock_setTZ 1


    I recently reworked DST settings, so this version will use two "statements" with "CLOCK_setDST" for the two switching times. You can start with begin or end of DST, since the statement will include "how much DST offset after this point".
    Every entry is "nth week" "month" "weekday" "time" "minutes to add"
    In my case it can be "pseudo" read as
    "on/after last (0) Marchs (3) Sunday (1) at 2:00 (2) add 1h / 60 minutes (60 ) and on/after last (0) Octobers (10) Sunday (1) at 3:00 (3) add 0 (= set DST to 0)"

    OpenW800 control panel showing local time, GPS data, active drivers, chip temperature, and WiFi status.
    After this you can use the clock as usual without NTP or any other clock source:
