Volumio Primo hifi edition bluetooth

Does anybody also have a problem either finding volumio on bluetooth on there mobile or tablet?
And when finding volumio on mobile and connecting bluetooth, the connection have dropspot
Either have reconnect or not even possible to connect again.

Maybe is the position where primo stand that can be the and the Bluetooth antenna is weak
Or do i have to attach the wifi antenna? Even so wifi bluetooth two different things in this matter

Hope someone can guide.

if your device is without WiFi antenna, Bluetooth will also have bad coverage… the WiFi/BT Module is a combined one, making use of the same antenna
