 I would like to use this chip nRF9160-SIAA-B1A-R now only as LTE modem. But the modem should be controlled by two external MCU. Please see figure.

&lt;p&gt;Our developers inform me that SLM can only listen to one phyiscal channel. You will need to share one UART bus using mux.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;&lt;em&gt;&amp;quot;Will need to verify with our developers.&amp;quot;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;Can you still ask from which modem version it supports?&lt;/p&gt;

[quote user=""]1- It is possible to impelmient as follows?[/quote]
&lt;p&gt;I can&amp;#39;t see any reasons for why it should not able to&amp;nbsp;implement this. Will need to verify with our developers.&lt;br /&gt;&lt;br /&gt;&amp;nbsp;&lt;/p&gt;
[quote user=""]2-&amp;nbsp;Does the modem firmware support that modem be controlled via two UART (I can talk to the modem over two UARTs)?[/quote]
&lt;p&gt;You will need to implement this by yourself as we do not have any examples for this.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;Kind regards,&lt;/p&gt;
