I am installing org.eclipse.kura.driver.ble.sensortag bundle and it is shown in kura.log my bluetooth interface is not found as shown below:

However, I am seeing my interface connected as shown below:

I think my problem is coming from that error. How can I fix it? Many thanks

Hi,

since Kura 3.1.0 the Bluetooth Service is based on the TinyB library and the BLE driver can be used only with this new lib.
It seems from the logs that the native library is not correctly loaded and this causes your exception.

What version of Kura are you using? On what device? Not every device is currently supported by TinyB because the lib has to be compiled for that specific hardware architecture.

Best,
Pier

thanks Pier for your reply.

I am using Kura 3.1.0 on raspberry pi 2. I guess TinyB is supported for raspberry pi 2?
