You will not have to make any changes in the FW, however you will need another nrf51 or 52 based device to use as a sniffer.</p><div style="clear:both;"></div>RE: iPhone 7 series dropping connection after approximately 40 secondshttps://devzone.nordicsemi.com/thread/162705?ContentTypeID=1Thu, 20 Dec 2018 15:23:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0d80ec75-d2c7-46a0-8582-2392add21434Aleksandar Kahriman<p>The only logs I have access to at the moment are RTT Viewer terminal logs from firmware side.
