Connecting to 3 BLE Devices to takes very long

[NorbertRoller]

I have to connect 3 devices and each need ~2.5 seconds for a full cycle (doConnect_Senso4s->connectToServer-Notification coming in)

I run this code for each BLE device sequential:
if(doConnect_Senso4s) // MAC+Service found {doConnect_Senso4s = false; // Für nächsten Durchlauf bereit machen if(connectToServer_Senso4s()) { debug_info("Success! we should now be getting Senso4s notifications!",1); } }

Adding the scan delay is on top.
I know that the devices are slow to connect, but I can not change this devices.

I was wondering if I could start the connectToServer simultaneously or if there is any other way to speed this up.

Many thanks for pointing me into the right direction.
