M malvin garabha Member Aug 31, 2024 #1 i have an esp32 dev kit that transmitts data through serial and a b4j program that reads the data , when i connect the esp 32 the b4j program does not receive the data i have to open another program like arduino serial monitor or termite and connect it to the esp32 and then get data and after that if i connect the B4J it can receive the data and i have to do this every time i start the b4j program .what could be the fault?
