    you can use the esptool lib on python
    I think you can do it on mos too
    But a flash usually results on overwriting your flash, so it shouldn't really be needed under normal circumstances

    but i'm cant flashing fw with new size of app. and after erasing full flash..
    DrBomb
    @DrBomb
    sorry, the app size
    Then you will need to reduce the FS partition size
    Liviu
    @nliviu
    Just flashed a device with APP_SLOT_SIZE: 0x1B0000 and default fs size.

    How did you define the APP_SLOT_SIZE?
    Sekilsgs2
    @Sekilsgs2
    ok. i'm try this size
    in makefile locally
    Liviu
    @nliviu
    What makefile?
    Sekilsgs2
    @Sekilsgs2
    mongoose-os/platforms/esp32/Makefile.build
    DrBomb
    @DrBomb
    So you're not building with the mos tool?
    Sekilsgs2
    @Sekilsgs2
    with mos tool - on local machine with local docker
    Liviu
    @nliviu
    It won't work like this.
    Either add --build-var APP_SLOT_SIZE=0x1B0000 to the command line, or add in mos.yml
    build_vars:
  APP_SLOT_SIZE: 0x1B0000   # 1536KB+192KB

    @Sekilsgs2
    hm. ok i'm trying now

    @Sekilsgs2
    thank this is working.. i'm think because this var need change in different places...

    Guys need some help about mjs - from js i'm can using all c functions compiled to elf or? i'm try using some functions from mgos_barometer.h but getting error a - wrong ffi signature.. 
    _crt_i2c1: ffi('void* mgos_barometer_create_i2c(void*, int, int)'),
    DrBomb
    @DrBomb
    And what is the signature of the function?
    Sekilsgs2
    @Sekilsgs2
    struct mgos_barometer *mgos_barometer_create_i2c(struct mgos_i2c *i2c, uint8_t i2caddr, enum mgos_barometer_type type)
    Sekilsgs2
    @Sekilsgs2
    after i'm put new folder mjs_fs and put api_baro.js into this folder in baromter lib and rebuild fw - this error go out - this mean that not all functions i'm can using in mjs - only that exported to ffi in compiled time and only if mjs_fs folder present...
    DrBomb
    @DrBomb
    Yes, you cannot ffi functions willy nilly. The ffi lookup table is made on compile time

    @rojer did you get a chance to look at the R4 Heap crash on boot?

    @mbresciani
    I know that the rpc-service-gattc is on hold but is there any place that I can get the esp32_bt_gattc.h file so I can learn a bit more about it?
    Mark
    @markterrill
    .... on hold ?
    I use it ...
    it's in the bt common library
    https://github.com/mongoose-os-libs/bt-common/tree/master/include
    https://t2fi.com/
    @mbresciani
    It doesn't compile any more and is not a priority.
    Mark
    @markterrill
    that's a surprise to me.
    oh my bad. yes, doesn't work
    https://t2fi.com/
    @mbresciani
    Yes, I read that someplace. Thanks for the link I should have checked there.
    Mark
    @markterrill
    sorry, got thoroughly confused with RPC via gatt
    ie server
    you're talking about gattc client
    https://t2fi.com/
    @mbresciani
    Yes

    Hi, the mg_connect_opts.ssl_cert is the path to the client certificate file, or is the actual content of this client certificate file?

    @nliviu: it's too much general error code... maybe i should enable some embedtls debugging to see more logs... is there option to debug SSL things?
    Liviu
    @nliviu
    Try to increase debug.mbedtls_level

    cc3220 i2c wont start automatically - need manual run mgos_i2c_create - why this not running automatically? maybe i2c cfg enabled after init all mgos deps?
