Thakn you for your answer! I tried to find the quickest way to get the data, and i have never thought about writing a PC application (Honestly i am not really good at thaht, i have never done it before) but i will try! Thanks for taking the time and answering me !</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/45277?ContentTypeID=1Wed, 17 Feb 2016 13:06:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b84a107-80fb-42de-93c1-254d62f1ccbeDavid Edwin<p>You can use the nRF Sniffer software to run on the nRF51-DK or nRF51-Dongle. However I would discourage the use of the Sniffer as a data collection method, as it needs to be setup etc. It may work for you and you may be satisfied with it, however there a no guarantees for sustained data collection.</p> <p>It may be simpler to write a PC application to talk to the HRM and ensure that all the data is collected. However I will leave that judgment to you.</p><div style="clear:both;"></div>
