https://devzone.nordicsemi.com/f/nordic-q-a/121148/ble-wi-fi-co-existence-on-thingy-91-xHi, The Thingy 91 X uses a shared antenna for BLE and Wi-Fi. I can see from the Hardware Guide and the schematics that there are several hardware connections between the nRF5340 SoC and the nRF7002 Wi-Fi companion IC to support wireless co-existenceen-USTelligent Community 13Mon, 05 May 2025 09:28:50 GMThttps://devzone.nordicsemi.com/thread/533876?ContentTypeID=1Mon, 05 May 2025 09:28:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:de8fab9c-9f2d-4e8d-93b0-73146e42983cCharlie<p>Hi Scott,</p> <p>Thanks for reaching out with your questions.</p> <p>It&#39;s not straightforward to make your current application work with the Thingy91X hardware design.</p> <p>The nRF5340 SoC needs to be used as the host in order to support automatic antenna coexistence with the nRF7002. However, in your case, the nRF9160 is acting as the application host, which makes this challenging.</p> <p>As an alternative, you could consider implementing application-level control to avoid conflicts. For example, you might have the nRF9160 send a UART command to the nRF5340 to disable BLE when Wi-Fi scanning is active.</p> <p>Best regards,<br /> Charlie</p><div style="clear:both;"></div>
