Im lunching mqqt example, getting constantly message No PING_RESP, disconnected, even though MQTT service functioning (reconnecting constantly, but still)
Ive added some debug lines in mqtt_client.c,

Code: Select all

ESP_LOGE(TAG, "\r\n in mqtt_write_data() \r\n Platform: %llu,client_tick: %llu, keepalive: %d,\r\n",
platform_tick_get_ms(),client->keepalive_tick, (client->connect_info.keepalive* 1000)/2);

and the reason as I see it is platform_tick_get_ms() does not work properly - it returns different values in different functions, and yes, they are not "ticking"

Log output:
