- My goal is: Update config from google cloud IoT
- My actions are: I have next code
static void my_gcp_ev_handler(int ev, void *evd, void *arg)
{
if (ev == MGOS_GCP_EV_CONFIG)
{
LOG(LL_INFO, ("MGOS_GCP_EV_CONFIG"));
struct mgos_gcp_config_arg *msg= (struct mgos_gcp_config_arg *) arg;
struct mg_str *s = &msg->value;
LOG_(LL_INFO, ("got command: [%.*s]", (int) s->len, s->p));
(void)evd;
(void)arg;
}
enum mgos_app_init_result mgos_app_init(void)
{
mgos_event_add_group_handler(MGOS_GCP_EV_BASE, my_gcp_ev_handler, NULL);
return MGOS_APP_INIT_SUCCESS;
}
- The result I see is: fatal error

- My expectation & question is: where error in my code? Anybody have example of work with google iot config and command?
