@OekoSolveMG Could you please try this solution: ``` cpp // Necessary include for testing the fix #include "driver/uart.h" void setup() { // for example, start Serial - UART0 Serial.begin(115200); //...

We have done a few updates to UART in the new Arduino Core 2.0.5 version. There are new functions that may help your applications in getting "real-time serial.read()": - `void...

I have tested the changes from PR #6930 that adds `HardwareSerial::setRxFIFOFull(uint8_t fifoBytes)` API. It solves this issue for sure. It allows Arduino to read byte by byte from UART as...

@guydvir2 - Could you please test your project with this WiFi setup code, and then let mw know the results: ``` cpp void setup_wifi() { delay(10); // We start by...

`WiFi.useStaticBuffers(true);` must be called before `WiFi.mode()` It will use WiFi Static Buffers and also increase the number of simultaneous connections to 8. This may improve the MQTT performance. Please try...

The drawback about using `WiFi.useStaticBuffers(true);` is that it will "eat" about 60K of HEAP on the application startup.

> error: 'class WiFiClass' has no member named 'useStaticBuffers' > WiFi.useStaticBuffers(true); > ^ Please use Arduino Core 2.0.3+ in order to have access to this feature. What is the Arduino...

Do you use Arduino IDE? For that, just go to Menu->tools->board manager

@guydvir2 OK, it is interesting. An improvement, but maybe not perfect. The latency is not due to the MQTT server? Or maybe some MQTT QoS setup... or Network issues from...

PPP has been removed from Arduino Core 2.0.0 to 2.0.1, if I remember. The reason is that it consumes a lot of Flash and users were complaining about the size...
