Hi Krishna,
Did you see my response on Feb 5? I am including here in case you
didn't get it. Let me know if you still have questions.

Hi Krishna,
Thanks for the report; I see the same behavior. The problem is that
both the BLE controller task and the UART poller task use the same task
priority: 0. A few things:
1. The bletiny app has been superseded by the btshell app. Both apps
serve the same purpose, but btshell is more up-to-date and has more
features.
2. The nimble controller really isn't meant to run in sim (i.e.,
hw/bsp/native). It builds, but that is just to enable unit tests to
run. If you want to use that dongle as your Bluetooth controller,
you'll need to switch to btshell, and then make a change to your
target's configuration:
newt target append <target-name>
syscfg=BLE_HCI_TRANSPORT_NIMBLE_BUILTIN=0:BLE_HCI_TRANSPORT_SOCKET=1
This disables the built-in controller, and configures the target to
communicate with your dongle via a Linux Bluetooth socket.
3. Just an observation: we need to fix some packages. All task
priorities should be specified with `type: 'task_priority'`. That way,
newt will complain about conflicting priorities at build time.
