We are testing with new made cuicuits. We use the same circuit schematic that worked with previous nrf9160s but small layout size. We tried to connect to NB-IoT networken-USTelligent Community 13Mon, 06 Jul 2020 09:32:53 GMThttps://devzone.nordicsemi.com/thread/258550?ContentTypeID=1Mon, 06 Jul 2020 09:32:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d3651d88-e651-4c91-8c33-8f1a2feef24aketiljo<p>Pins 104 to 127 are clearly marked in the<a href="https://infocenter.nordicsemi.com/topic/ps_nrf9160/pin.html#reference_hyx_mmw_pv"> pin assignment</a> list as do not connect. Some of them are internal test pins so grounding these can give all sorts of errors.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/258426?ContentTypeID=1Sat, 04 Jul 2020 07:15:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:969710ad-666d-4f43-8229-84d5269817efxuan0802<p>We tried to disconnect those pins and connect again to the network.</p> <p>It can connect again.

Some pins are open (not connect to anything in version 1) are connected to ground in this version. Those pins are 113, 111, 106.
