Iam using nrf52840 development board, developing software using zephyr.
In software development iam using bluetooth as a peripheral and uart in interrupt mode(to get data from other module), when iam trying to run both interfaces the board is getting hang without any errors and iam included watchdog timer so after sometime it is restarting.
When iam trying same fuctionality without using interrupt for uart and bluetooth, after some time device is stopping advertisments but uart is working fine.
