There seems to be no data received via bluetooth.
Secure it in such a way that it creates a list only if the variable "global input" is not empty.
Kindly tell in detail
So the problem is where you are trying to split it. And According to error it shows ,
get global inputisn't empty. Only issue is it does not have "|"
Tell more what exactly you are trying to do , so maybe we can help
After reading data from BT, add IF conditional block. If not empty global input, then ....
it sending the data but shows this message
Does not receive data. Or there is no | sign in the data.
Do such a test. Read data from BT and do not split it, just enter it into the text field and see what you have received.
then how to solve it
i am trying to get reading from arduino via bluetooth kindly solve this issue
Alternatively, try this block:
Why do you want to split the data ? According to your code there should be 4 things (or words or something) and you split them. All I see is 2 things , in the error.
i dont know much about it .It was working pecfectly with three sensors now i added fourth one it start showing this message
okay what all things are you measuring ? the more deeply you tell better it would be to figure out the problem
Which is the new sensor added ?
PH , turbidity ,temperature and humidity
Show arduino code after adding fourth sensor.
ii added ph sensor now
Problem could be here ...
I won't be able to help in arduino code , sorry
@powerusers can surely help you out
Also please post your arduino code just like @Patryk_F told
It is possible that in arduino you not added another "|".
Paste the arduino code here.
