52840 WDT causing confilict

[Avadacadabara]

Hi,

I added watchdog to usbd_ble_uart sample code.

BLE connection breaks when sending data to DK via USB.

What might be the cause?

Thanks.

I suggest to start by taking a look at the watchdog example:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/hardware_driver_wdt.html

I would have started at looking at the reload value you have set (NRFX_WDT_CONFIG_RELOAD_VALUE), and possible increase it. Secondly look at how often you are able to call nrf_drv_wdt_channel_feed(), and make sure it is called more frequently than set by the reload value (NRFX_WDT_CONFIG_RELOAD_VALUE).
