Hi guys. Can anyone help me in obtaining the local random UDP port when i'm creating a new UDP connection using mg_connect()?
Is that available somewhere in the struct mg_connection parameter in the event callback method?

@abhishek125

As far as i know every esp has unique MAC address which also serves as its client id, but I am facing duplicate client id issue with aws provisioned esp devices. I confirmed the same with aws support and cloudwatch logs.could anyone please give me any clue how this kind of issue is possible.

i am using nodemcu esp8266 with mongoose os

@abhishek125 - Unfortunately you are in the wrong conversation, this is for mongoose, Cesantas web server, not mongoose-os, but there your question should be posted.

Hi Guys,
Currently I'm working on esp32 using mongoose
I tried to compile free rtos with mongoose
but I'm able to compile but module were continuously getting restart
for ref:

void mg_task(void *arg) {
  printf("mg_task started\r\n");
  while (1) {
    mgos_msleep(100);
  }
  vTaskDelete(NULL);
}
enum mgos_app_init_result mgos_app_init(void){//void user_init(void) {

  printf("Free RAM: \r\n");//, system_get_free_heap_size());
  xTaskCreate(mg_task,"mongoose",1024, NULL, 0, NULL);
  printf("%s", "hello, my task");
              //MG_TASK_STACK_SIZE / 4, /* in 32-bit words */
              //NULL, MGOS_TASK_PRIORITY, NULL);
 //xTaskCreatePinnedToCore(&my_task, "tskmad", 2048, NULL, 5, NULL, 0);
 // while (1);
  return MGOS_APP_INIT_SUCCESS;
}

please help for flashing esp01 in MangooseOS

Esp01 doesn’t have enough flash for Mongoose OS

Also, this is the wrong channel for Mongoose OS

@majorninth

I have a problem connecting to aws with a esp32 dev kit. I have existing certificates, key and policy for an existing aws connection that I use for testing various wifi boards. I setup my esp32 kit to point to my aws site and filled in all the proper information in the config files. AWS gives me a -2700 error (bad certificate). I have no problems connecting with non mongoose boards and I have no problem connecting to my own MQTT server (with different certs and key). Is there anything special about mongoose that wants its own type of cert/key rather than something that was generated directly in the aws cli rather than using the mongoose aws setup iot default command?

@cpq Sorry for the late reply. (Regarding the memory leaks question). Here is the valgrind-log gist again https://gist.github.com/karthikdesai/6380c611062e38c1a7944d15ef3c12eb
The server was run for around a min. And from the log we see that:

mg_mgr_init_opt (mongoose.c:2609) (on the log https://gist.github.com/karthikdesai/6380c611062e38c1a7944d15ef3c12eb#file-valgrind_output-log-L299)
mg_if_create_iface (mongoose.c:3648) (on the log https://gist.github.com/karthikdesai/6380c611062e38c1a7944d15ef3c12eb#file-valgrind_output-log-L601)
mg_http_create_proto_data (mongoose.c:6030) (on the log https://gist.github.com/karthikdesai/6380c611062e38c1a7944d15ef3c12eb#file-valgrind_output-log-L1859)
mg_create_connection_base (mongoose.c:2739) (on the log https://gist.github.com/karthikdesai/6380c611062e38c1a7944d15ef3c12eb#file-valgrind_output-log-L2508)
functions had 'still reachable' loss record on valgrind. Can this be some how fixed or is there some steps that i have missed? Thanks!

Sergey Lyubka

@cpq

@karthikdesai yes, please make sure there are no leaks from your own application first. When you can show valgrind output with only mongoose records, we might take a look.

Karthik Desai

@karthikdesai

@cpq Unfortunately these leaks are from other libraries i have no control over :(

Sergey Lyubka

@cpq

@karthikdesai i am not sure that mongoose is to blame here - it could be that your application is guilty, not mongoose

if you're convinced that mongoose is guilty, then provide a failing test in test/unit_test.c , we'll take a look

Pim van Pelt

@pimvanpelt

hey :)

Mark

@markterrill

howdy.

so is the HA library a mqtt client ?

Pim van Pelt

@pimvanpelt

just FYI, this is the underlying library Mongoose

the thing you're looking for is Mongoose OS

Mark

@markterrill

yeah

Pim van Pelt

@pimvanpelt

but yes, I started a library a few weeks ago

Mark

@markterrill

have any public code ?

Pim van Pelt

@pimvanpelt

because my wall switches and relays and thermo/hydro/baro etc sensors want to be exposed in my HA

Mark

@markterrill

oki

Pim van Pelt

@pimvanpelt

and I didn't like the alternatives like esphome and tasmota

I haven't really finished the library yet but I am willing to put it online for you to play with

some caveats: before I submit it to mongoos-os-libs/ it needs a few strong use cases

currently all it does is expose gpio and a few sensors

and it's not complete (and as well I have not run it in production, only in a few test instances where it seems to work well with MQTT auto discovery)
