The log for the communication issue is as follows: I&#39;m using a Nordic Thingy 91 Rev. 1.4.0 and the hci_lpuart anden-USTelligent Community 13Thu, 28 Sep 2023 13:47:16 GMTRE: UART communication between nrf9160 and nrf52840 on Thingy91https://devzone.nordicsemi.com/thread/448179?ContentTypeID=1Thu, 28 Sep 2023 13:47:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b3ac4bf4-42c5-4945-a5af-1ca0e6d4d0fcSam D<p>Hi Navid, I am Noridc&#39;s Technical Sales Engineer responsible for Eastern Canada.

Our developers are working on the issue but we have no timeline at the moment. The best suggestion is to not use the Thingy:91 for LTE BLE Gateway.&nbsp;<br /><br />Please see this case as well&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/102456/lte_ble_gateway-fails-with-ncs-2-2-and-thingy-91-rev-1-6-0">lte_ble_gateway fails with NCS 2.2 and thingy:91 rev 1.6.0</a>&nbsp;</p> <p>Kind regards,<br />Øyvind</p><div style="clear:both;"></div>RE: UART communication between nrf9160 and nrf52840 on Thingy91https://devzone.nordicsemi.com/thread/448019?ContentTypeID=1Wed, 27 Sep 2023 17:02:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bdde8186-feba-4121-ae30-49d634004d77Navidh307<p>Thank you for your response.</p> <p>Is the issue limited to this specific example for Nordic Thingy91?</p> <p>If it isn&#39;t, I would appreciate your guidance on which example would be the most appropriate starting point for my project, which involves UART communication between the nRF9160 and nRF52840 within the Thingy91.</p><div style="clear:both;"></div>RE: UART communication between nrf9160 and nrf52840 on Thingy91https://devzone.nordicsemi.com/thread/447921?ContentTypeID=1Wed, 27 Sep 2023 11:19:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ade9aab4-d4a7-496e-a7cc-84f0301add1e&#216;yvind<p>So first I would like to inform you that the LTE BLE Gateway is designed for the nRF9160DK, not for the Thingy:91. We know there are issues with the UART on the Thingy:91 when running the LTE BLE Gateway.&nbsp;</p> <p>I would recommend not using the LTE BLE Gateway with the Thingy:91 with the current state i.e. not supported in the sample.</p> <p>Kind regards,<br />Øyvind</p><div style="clear:both;"></div>RE: UART communication between nrf9160 and nrf52840 on Thingy91https://devzone.nordicsemi.com/thread/447882?ContentTypeID=1Wed, 27 Sep 2023 08:36:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b5b52a3e-a396-42ed-9773-5481ceba9d5b&#216;yvind<p>Hello, sorry, a little too much on my plate the beginning of this week.
