Hi,

I assume this is referring to the peripheral radio transmitter example in the nRF5 SDK? Which version of the SDK are you using, and which IDE/toolchain and which version of it are you using?

I have seen similar issues before using newer versions of Segger Embedded Studio. If that is what you are usign, I recommend you use the version that is mentionned in the release notes of the SDK. For isntance, if using nRF5 SDK 17.1.0, I suggest you use Segger Embedded Studio 5.42a. See this thread for more details.
