Self solved. It was because webserver handler blocks dequeuing MPU 9250's FIFO more than 10ms and the FIFO is filled around 10ms. Solved by using multi-core approach. Dual core is a lot better than a single core... xTaskCreatePinnedToCore( handleWebThings, /* Function to implement the task */ "handl...

However, on the exact timing of web request, bytes read on that timing is changed. My current code just simply shows template webpage an...
