Hi @Yatheesha Did you use esp_http_client_read to read the data? If yes and you provide the len parameter more than the number of bytes to read, then http_client will wait for the end of the timeout to return. You can use esp_http_client_get_content_length to know the exact number of bytes to read b...

Since this post was originally made last year, the esp-mqtt library has been integrated into ESP-IDF. Is the esp-mqtt library thread safe? I don't find locking mechanism in the esp-mqtt library code. So I'm wondering if it is ok to call esp_mqtt_client_publish() in another task? The example code ca...
