Re: SNTP returns same value each time

Hi gtjoseph, yes, it does leave the loop and after that, the user provided callback is called. I suspect, there is some error when parsing received values. For some reason lwip_ntohl is macro for lwip_htonl . Should not that be individual function transforming from big-endian (received from NTP serv...

FreeRTOS task integration

Hi guys, I am programming a device, which should get some values from sensors and send them over the MQTT protocol back to the server. Right now, there are two ways how to connect to the internet - external LTE modem over pppos and WiFi integrated right on ESP32. I created two tasks - MQTT and CONN....

Re: I2C wire library porting on ESP-IDF

I would check datasheet for the sensor. Basically you are interested in sensor's I2C address. Some devices have only one pre-defined address. Some have multiple, which are configurable by the user (switch on the device or different wiring of the sensor itself). Next, check this example of I2C librar...
