Good day everyone, I am developing a project using Arduino Uno with DTH Sensor AM2302 and Nextion 4024T032 for display. Now I’m aware that there are many examples and tutorials on the net on this project and I did watch and refer from them. Checking all the procedure and reviewing it, I can’t seem to find whats wrong with my version. After following steps and process, I come to face an error like this. After compiling all codes for Arduino and Nextion, connecting them and running it, the Serial Monitor prompts the message " ⸮⸮⸮⸮⸮⸮bkcmd=1⸮⸮⸮page 0⸮⸮⸮ ". I don’t know what it means or even what caused the error but due to this the adruino can’t communicate with the nextion display.
PS: Regarding on my code I notice that prompt error is the result of nexInit() function in the setup. When I remove it the error disappears but leaving the arduino and nextion no communication whatsoever.
I know it may seem a simple problem and I guess I just missed a crucial part for setting both of the device. But I really don’t know where to start looking now. Wish you could all give me some advice or insights. Thanks.
I have attach the Serial Monitor Error Output.
