Could you explain how&nbsp;nRF9160-DK board interfaced with STM32?</p> <p>Do you mean you are using nRF9160DK J-Link OB to program STM32 chip? I am not sure if this is possible, you need to get advice from STM on how to program their chips.</p> <p>or you mean you are programming nRF9160? nRF9160 only accept programming modem firmware and application firmware. I am not sure why you have three files.</p> <p>Best regards,</p> <p>Charlie</p><div style="clear:both;"></div>
