Hi, I finally got a graph to appear on my phone using an arduino nano, hx711 and a hc05 using app inventor code and the serial.write function in arduino. However when it starts it is very responsive but as time passes it gradually gets slower and slower to respond. Is there a way of flushing the bluetooth buffer in app inventor.
The buffer is not an ever-growing region of memory. Are you sure the issue is on the App side? If the Arduino is getting hot, that would fit the same symptoms - try keeping it cool with a fan.
I tried the graph on the serial plotter via bluetooth in the arduino ide no lag, so pretty sure its the app inventor side.
Maybe the Arduino send speed is very fast for the App.
Create a delay, for example 10 in the Arduino code and a Clock interval, for example 5 in App.
They’re both set at 100ms I’ll try and run the app at double the Arduino speed. Thanks by the way
Well it looks like we have a winner it works like a dream now many many thanks!
hello
iam trying the same project of hx711 graph .. would you please share your mit and arduino code? .
thanks a lot
