    Thank you Rojer. I have one more question regarding how daylight saving works in mongoose. Is device rebooted after time is changed?
    Sergio R. Caprile
    @scaprile
    AFAIK there is a "time changed" event callback you can register. I guess this applies; however, I live in a country where DST is not used and haven't checked. Take it with a grain of salt. This event is fired on SNTP adjustments, for example.

    @DrBomb
    I believe, and I'm not completely sure this is the case. That the DST jump will not trigger or reboot the system
    DST is only applied when you need local time, or for example, on cron jobs
    And on those cases, I think if the invocation time lines after the DST, the time libs will make sure to get that sorted out
    But when you call mg_time you're getting the UTC, unix time, as you should have
    hence why it isn't affected by DST
    I've used the cron lib for a couple years now on the US/Central timezone and DST has been adjusted automatically

    cron jobs are based on UTC time.
    mgos_cron.c:231         Next invocation: 1617036555 [2021/03/29 16:49:15 UTC]
    And yes, DST is applied when you need local time AND sys.tz_spec is set.
    DrBomb
    @DrBomb
    cron job messages show a timestamp in UTC, but they will follow the timezone set on the tz_spec
    @nliviu

    @scaprile
    So hence DST "jumps" will not trigger time change events... now I know, thanks. It makes sense to just change the conversion factor to localtime...

    If I set oneshot timer, for example mgos_set_timer(1000, 0, &timer_cb, NULL) should i store timer_id and call mgos_clear_timer(id) to release internally allocated memory of this timer?

    What is meaning of bool return value of mgos_mqtt_global_connect?
    Sergio R. Caprile
    @scaprile
    I've found that if you hold a timer handler and later you cancel the timer as you suggest, you have to also invalidate your handler (timer_id = MGOS_INVALID_TIMER_ID). If you setup and cancel several timers you may get repeated ids because they are reused (iirc).
    If you don't need to cancel the timer, it will clear itself when it fires (unless it repeats, of course...)
    Clearing an already cleared (automatically or cancelled) timer is safe, but since ids are reused and you started another timer in between... you end up cancelling the new timer and not the old one (iirc, again)

    Hi Everyone, I have been fighting an issue with Little FS and the Winbond W25Nxxx device driver / VFS driver for some time now. Using an ESP32-WROOM-32U with a W25N 2 Gbit device (I have not tried the 2 Gbit) I am able to start Mongoose and create the file system. But if I open a file using fopen() and start appending data, after just a few hundred bytes LFS reports the device is fill. Also, if I create a number of small files, after about 18 or so, it reports that the superblock is full.

    Does this ring any bells?

    Oops.. I'm using the 1 Gbit device, have not tried the 2 Gbit

    can someon help me out with cron task in mongoose ?
    Any examples??
    Liviu
    @nliviu
    @Anshu694 Assuming you have added the cron library in your mos.yml
    #include "mgos.h"
    #include "mgos_cron.h"
    
    static void cron_1min_cb(void *user_data, mgos_cron_id_t id) {
      time_t now = time(0);
      struct tm *tm = localtime(&now);
      char t[32];
      strftime(t, sizeof(t), "%T", tm);
      LOG(LL_INFO,
          ("Uptime: %.2lf, time: %s, free_heap_size: %lu, min_free_heap_size: %lu",
           mgos_uptime(), t, (unsigned long) mgos_get_free_heap_size(),
           (unsigned long) mgos_get_min_free_heap_size()));
      (void) user_data;
      (void) id;
    }
    
    enum mgos_app_init_result mgos_app_init(void) {
      /*
       * Add a cron job at every 5 seconds of a minute.
       */
      mgos_cron_add("5 */1 * * * *", cron_1min_cb, NULL);
    
      return MGOS_APP_INIT_SUCCESS;
    }

    Supports Mongoose OS secure boot on ESP32?
    gadget-man
    @gadget-man
    Moa doesn’t yet support secure boot. I think it’s on @rojer list but no timescales unfortunately.

    Hello! I'm trying to configure a ATEC608A (a barebone and the Qiic by Sparkfun) and get this error back : "No handler for ATCA.GetConfig". I dont find any good results on google. Any ideas ?
    And the error occurs when i try to pass the atca-set-config command : mos atca-set-config proto-config.yaml --dry-run=true

    @DrBomb
    Means that the firmware you're using does not contain the RPC command it is trying to call
    You will have to add the lib to your app
    The latter is most likely the one that registers the methods you're missing

    @Enophi
    @DrBomb Thx a lot :) I was totally missing the libs :/

    Hi, dumb question... how do I interpolate a string into a variable? do something with that variable and then make sure that variable does not take up any buffer / ram space?? "key: value, key:value2, key:value3" ?
    DrBomb
    @DrBomb
    There are many ways. but it depends on the format you're using. If it is json you could use cesanta's json parser, frozen, but it really depends on what you have to work with
    and regarding the question of memory, that's something for you to figure out
    Ivan Polchenko
    @i5okie
    I can't figure out how to use frozen.

    or rather, I got it working. But my esp32 keeps doing core dumps after a few seconds.

    Hello, is there in mongoose os option to set AP advertising beacon timeout? Like send beacon every 500ms or every 1s.

    It works fine :) All you need to do is to add mos.exe to PATH variable

    Hello everyone. I'm stuck with an ATECC608A. I set the sample config file and lock the config/data zone. I re-provisionned the chip with the command : mos aws-iot-setup --use-atca .... The process succeed but when i check the log, there is a invalid SSL key error. When I check the config device for the mqtt section, there is "ssl_key": "ATCA:0" as it suppose to be. Do you have any ideas ? Maybe it's because of the re-provision. Thank you in advance for your help.
