I currently have a GUI that communicates via Bluetooth. The issue is, that there is no delay when I use a Desktop, a Laptop, and even a Raspberry Pi 3B+, but now I am using the latest Raspberry, the Raspberry Pi 4B in particular, there is a 5-8 secs delay when sending and receiving. For all computers, I use processing for the GUI.

If anyone has any idea to solve the delay issue, that would help a lot.

Thank you
