In the end it is just a transpo= rt layer. The real work happens in the Bluetooth core. However that said, w= e never had a limit on number of LE connections. Nothing there was ever enf= orced. I was afraid of that... I guess that means that there must be different versions of the dongle. We're working with many devices and ordered many dongles over the last 2 years. It's possible the manufacturer slipped in some changes over that time. I'll see if I can confirm that. > If you do not need BR/EDR, you can switch that off and it might free the = radio resources you need for the many LE connections. However a 3.13 is not= really getting you there. It might actually work there, but I would only t= rust a 3.18 or 3.19 kernel here. Yeah, it's be nice if everyone was on mainline, but unfortunately I'm stuck using 3.4 for the embedded device I'm using. How do I shut off the BR/EDR aspects of the dongle? I'm not sure if it'd help, but it's worth trying.
