https://devzone.nordicsemi.com/f/nordic-q-a/113317/nrf9160-external-sip-serial-communicationHi, We have our custom PCB with an nRF9160 SIP that is connected to a nRF9161-DK via P20. I have a couple questions about this setup. Is it fine for us to program the external nRF9160 SIP with a nRF9161-DK? We&#39;ll soon upgrade to the 61 chips,en-USTelligent Community 13Wed, 24 Jul 2024 13:06:49 GMThttps://devzone.nordicsemi.com/thread/495423?ContentTypeID=1Wed, 24 Jul 2024 13:06:49 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6ae1a4a3-d236-415f-af77-82d3ef7f6ff8Kazi Afroza Sultana<p>It&#39;s great to hear that it is working now.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/495320?ContentTypeID=1Wed, 24 Jul 2024 03:26:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1134ba0c-b186-4c3d-9e5d-7bfa2f9b05c6taylor_ca<p>Managed to get it all working using an external FTDI and updating the device overlay with our UART GPIO pins.</p><div style="clear:both;"></div>
