Bluetooth LE issues


I’m experiencing some issues with a Bluetooth LE device. The app doesn’t find the device even if bluetooth is ON and the device is already paired. I’m using the latest build for the Banana Pi M64.

If I switch off the bluetooth first, the app asks for bluetooth to be enabled and then it works perfect. It finds the device and connects without any issues. If I leave Bluetooth ON and try to connect again to the device it won’t find it. The device doesn’t even start automatically because it supports Bluetooth LE and so with an Android smartphone.

Does anybody have experience with Bluetooth LE devices? Did you get a device to work without issues?

Thanks for your help.
