bluetooth init error -90

Smitha Ratnam <s.ratnam@...>


We are trying to use the silicon labs thunderboard sense2 SLTB004A device with bluetooth. 
When we program the device the zephyr beacon sample, we get the following error:

* Booting Zephyr OS build zephyr-v2.5.0-3011-gb61c23943c6f  * Starting Beacon Demo Bluetooth init failed (err -19) [00:00:00.007,000] <err> bt_hci_core: No HCI driver registered
What are we supposed to do to get the bluetooth on the device initialised?
Does Zephyr support the device for bluetooth?

Thanks and regards,
