Same incompatibility overhere... The exported BSEC Config File from BME-AI-Studio is not recognised by the Development Kit App v1.1.3. In BME-AI-Studio it also mentions "Compatible with Development Kit Firmware version 2.0.5 and AI-Studio Mobile App 2.0". I tried to change filenames from .config to .conf and others things, unfortunately without success. That means the created algorithm can not be checked/tested with the mobileApp. Maybe the created .c and .h files can be used in a production_sketch!? I hope Bosch developers can update the issues soon. ... View more

I got news! Using Board manager to downgrade ESP32 Espressif Systems to 2.0.3 gets it down to 1249317 bytes (95%) in Arduino IDE 1.8.13. (Arduino IDE 2.0.3 did not let me change the board library for now) That is not mentioned in the Quick Start Guide, but you mentioned it in a post earlier. Thanks! ... View more

Hi Minhwan, unfortunately that makes only a few bytes difference. Sketch uses 1399397 bytes (106%) of program storage space. Maximum is 1310720 bytes. ArduinoJson (6.19.4) RTClib (2.0.3) SdFat (2.1.2) Compiled with Arduino IDE 2.0.3. But also Arduino IDE 1.8.13 results in same bytes count. So we need to shrink something down, or clever use the SDcard storage(!?) in a new bme68x_demo_sample.ino version. ... View more

Hi, Today I received my BME688 X8 Dev Board and ran into the same problem. The latest bme68x_demo_sample cannot be flashed on the ESP32 Feather because it is too big. (Sketch uses 1399613 bytes (106%) of program storage space. Maximum is 1310720 bytes.) Downgrading libraries only saves up a few bytes... Is a compacter release coming soon? Or is there a simple workaround rewriting (perhaps only commenting out) some files? The only flashable logging example is "bme688_dev_kit" from de BME68x Sensor Library, but that creates a .csv file which cannot be used in BME AI Studio. (I run that one now 24h to stabilize the sensor, is that okay, or will it generate too much heat and damage the sensors?) ... View more
