Hi everyone, I’m looking for a way to send the pressed item of a list via Bluetooth from the app to an Arduino.  
I spent all day searching through community posts for a solution but couldn’t find anything.  
Can anyone help me?  
Sending does not give an error (I change the color of the items specifically to check), however the transmission is really very slow and takes several minutes (it doesn’t always happen).  
I specify that other transmissions occur correctly, only this one has this problem (the uuid characteristics are correct). Thanks for the help.

Hi @fauloca24xo6d Does it send any faster if you simply add a string to the data being transmitted to the device?

What information is in the simple list when it is set to the app variable `file_prem`?
