Yes, you can connect multiple BT devices at a time. They will share the bandwidth available, but it is usually enough to not limit one of them.

Hi Harry and thanks for the quick answer.
So i can connect both an bluetooth gps antenna + the ODB blueooth ??? it seems akward that the phone will connect to 2 devises at the same time.
I already bought the recommended OBDLINK MX BLUETOOTH
Now which GPS bluetooth antenna would be recommended for my sony? but this is only if you are sure that can connect to 2 devices at the same time. I dont even understand how it would be possible as everytime i select one bluetooth device on the list the phone will disconnect from the existing one

That's part of the Bluetooth specification and is working.

Recommended GPS accessories are listed on

You can join one WiFi network on top of the BT connections. So 1 HERO - yes, 2 HEROs - no. That's a general limitation with action cams currently. They create their own networks. In case you want to control more than one, GoPro's remote control is needed - it uses some proprietary network protocol.

i have the remote but i guess that would not be started by HLT anyway right? I will just start the back cam manually no big deal
thanks Harry

LapTimer does not need Internet access to work. Just make sure you load your track set at home are while the GoPro is not connected. In case you are experienced with network configurations, you can configure it in a way the GoPro is not set as the default gateway. This will allow the phone to access the Internet using mobile data while being connected to the GoPro.
