https://devzone.nordicsemi.com/f/nordic-q-a/89383/icarus-iot-board-with-stm-f401reI am working with STM32-F401Re with IKO1A2 shield on it as well. I implemented the machine learning core on LSM6DSOX and I get the data of that accelerometer on STM32 F401re. Now, I want to transfer that data on ICARUS Iot Board so I can receive the dataen-USTelligent Community 13Tue, 28 Jun 2022 14:07:17 GMThttps://devzone.nordicsemi.com/thread/374574?ContentTypeID=1Tue, 28 Jun 2022 14:07:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b958f85c-f25a-42f9-b181-39ec8cf7320bJONATHAN LL<p>Hi,<br /><br />You could use something like the SLM exampmle on the nRf9160/ICARUS and have the STM32 be the master. <br /><br /><a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/doc/slm_description.html">https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/serial_lte_modem/doc/slm_description.html</a> <br /><br /></p> [quote user=""]How can i use the second UART for lsm6dsox and Icarus iot board?[/quote] <p>Is this the UART on the STM32 or the 9160 you are refering to?</p> <p><br />Yorur main goal is to transport the sensor data to the 9160 so that it can be sendt to the cloud?<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
