Raspberry Pi connection

[proudRestaurant0]

Hi, thanks for the awox-meshlight project. It has been really helpfull.
However, someone earlier pointed out that it can be (and will be on the raspberry pi) a bit slow. Are there any options to make the connection faster? I want only my raspberry pi to control the light so I thought of just not disconnecting but that threw an assertion Error...
Is it possible to use 'normal' bluetooth instead of BLE? Or change the address type? I get this error randomly:
Failed to connect to peripheral A4:C1:38:21:28:92, addr type: public
Sometimes it connects, sometimes it does not. Do you have any clue?

Thanks in advance!
