Hey everyone, the following refers to the Arduino_BHY2 library as well as the Bosch Sensortec BHY2-Sensor-API. The BHY2-Sensor-API exposes virtual sensors like a barometer with sensor ID BHY2_SENSOR_ID_BARO. According to the datasheet of the BHI260, this virtual pressure sensor requires an external sensor like the BME280 or BME680 or BMP280. The Arduino Nicla Sense ME features the BHI260, a BMP360 pressure sensor and the BME688 which itself has an integrated pressure sensor. However, I could not find which pressure sensor is integrated in the BME688. Since the Arduino_BHY2 library is a combination of the BHY2-Sensor-API and the Bosch-BSEC2 library which both expose a virtual pressure sensor, to me it is not clear, which pressure sensor is used. According to the datasheets of the BMP390 and the BME688, the relative accuracy of the BMP390 should be superior to that of the integrated pressure sensor in the BME68 and I would like to ascertain that the correct sensor is used. I would highly appreciate any clarification on the distinction between the two mentioned pressure sensors on the Nicla Sense ME. If anyone is familiar with the Arduino_BHY2 library, could you please explain how to configure parameters of the pressure sensor (whichever is used) other than sample rate and latency. Best regards, Robin

Hi everyone, it seems the download links for the BME AI-Studio software at https://www.bosch-sensortec.com/software-tools/software/bme688-software/ are broken. Could anyone please look into this? Best regards

Hello, thank you for your help and updating the documentation. The method "Using the Sketches as a Step Stone / Agent" worked perfectly fine for me.

Hello, now I finally have access to the firmware but I am still unable to upload it to the BHI260AP flash. I followed the instructions on uploading firmware to the Nicla Sense ME using OTA via BLE in the beforementioned documentation. I can connect to the board but when I press "Upload" the connection status will change to "Disconnected" after ~ 1 min and the board wil not be visible until restarted. A progess bar appears but no progress is made. Reading and configuring the sensors in the web interface works just fine. Also, I tried with Microsoft Edge and Google Chrome on both Windows 10 and Ubuntu. Using the built-in tools in the Arduino IDE for updating the NRF52 chip works as well, although uploading the NRF52 firmware via BLE leads to the same result as described above. Could you please verify that firmware updates using OTA via BLE for the Nicla Sense ME as well as the BHI260AP work for you and hint me on what I did wrong? Regards

Hi everyone, the Niclas Sense ME documentation states that the pre-programmed firmware of the BHI260AP chip does not support the self-learning AI features yet. However, a different pre-built firmware called 'Klio' is available for the self-learning AI core. Where can this firmware be downloaded? Best regards
