Then the BLE examples shouldn&#39;t work, only the ANT examples and examples like blinky. Please edit the question and include the complete laser markings on the nRF51422.</p> <p>Edit: QFAAC0 is the first IC revision of nRF51422. It is very old, and comes with a preflashed stack. It cannot be erased. Even if we could, I would still recommend you to get the latest revision, because this is the revision that is available if you go into production. (sorry for the late edit)</p><div style="clear:both;"></div>
