Thingy91 Simple UART Example Between NRF52840 and NRF9160https://devzone.nordicsemi.com/f/nordic-q-a/87699/thingy91-simple-uart-example-between-nrf52840-and-nrf9160I am developing for a Thingy91 and NRF9160 DK NCS v 1.9.1 I was initially using the LTE_BLE_Gateway sample with the NRF52840 running the hci_lpuart sample. and that appears to work well, but we want more control over 52840 chipset. Is it possibleen-USTelligent Community 13Tue, 10 May 2022 07:38:57 GMTRE: Thingy91 Simple UART Example Between NRF52840 and NRF9160https://devzone.nordicsemi.com/thread/367073?ContentTypeID=1Tue, 10 May 2022 07:38:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d2f5339f-b31f-43a3-b141-d0a63142b0a5ovrebekk<p>Hi David</p> <p>It should be fine to use a direct UART connection between the two devices, you just need to configure this equally in both chip so they can communicate properly.&nbsp;</p> <p>If you look at the <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/peripheral/lpuart/README.html">LPUART sample</a> you can see how you can implement an LPUART interface without running any higher level protocol like HCI on top, allowing you to send raw data.&nbsp;</p> <p>Best regards<br />Torbjørn</p><div style="clear:both;"></div>
