[quote userid="69599" url="~/f/nordic-q-a/48647/ble-debugging-on-nrf52"]Once i put a breakpoint in the code and if i want to proceed further, it won't let me and throws an error.[/quote]

That is because a traditional, "halting" breakpoint completely stops the CPU.

This means that the SoftDevice will miss its timing requirements - and crash.

So you really can't use "halting" debug with a SoftDevice.

Instead, you need Monitor Mode Debug
