Further investigation - I suspect this is the MAC BT stack/onboard BT not playing nicely with the ASUS BT400. Playing around at the following site seems to indicate that pairing occurs immediately ( blue light still flashing ) but the Service and Characteristic requests are stalling ( and the solid blue light ) until I sleep the screen ( thereby cutting the onboard BT ?? ). I will try permanently disabling the onboard adaptor. Paired immediately: Live Output After sleeping/waking screen (solid blue): Live Output

Since I can find no similar reports I am putting this down to a bug within my particular MACOS version / install / setup - a later OS version is working just fine. |

I have found a fix to my ( possibly particular ) connection problems where the device pairing request from Pybricks Code either times out or takes minutes.
I’m using Chrome 128 on an iMac and MacBook Pro both with MacOS 10.15 with BT 4 dongle. Tested with city and technic hubs.
I realise this is old hardware / OS with BT 2.x built in but I cannot tell whether this is the issue so I thought I’d report in case any newer computers are reporting similar issues.
FIX: I have found by accident that sleeping the display ( hot corners ) during the pairing activates the request immediately. I have require password set to 1 minute so it unsleeps immediately I move the mouse and works perfectly from then on. This is repeatable and works the same on both of the computers and both hubs.
Discovered on the MacBook when I closed it in frustration and it connected 😬 🎉
I have tried to connect using a web LE demo page but not sure I have the correct GATT service descriptor - just going through the web Bluetooth API spec atm.
