Hi, there!! I am working on a project in which I am interfacing BME680 to ESP8266 Node MCU.
To get the calibrated sensor value of BME680, I have installed the library BSEC(BOSCH Sensortech Environmental Cluster).
I have followed the steps given in the tutorial but I am using ESP8266 Node MCU V2:
[https://bluedot.space/tutorials/how-to-measure-indoor-air-quality-iaq-with-the-bme680]/
But, while compiling I am facing an error:
1.
c:/users/user/appdata/local/arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/3.1.0-gcc10.3-e5f9fec/bin/../lib/gcc/xtensa-lx106-elf/10.3.0/../../../../xtensa-lx106-elf/bin/ld.exe: C:\Users\user\AppData\Local\Temp\arduino\sketches\B7141D2A4CA07993157E1BD8D6875821/basic.ino.elf section .text1' will not fit in region iram1_0_seg'.
-
At first, the COM port was detected, but after trying to upload the code sometimes, it throws the above error and the controller disconnects many times.
-
When connecting the device to a different port the COM port does not change.
Please look into the topic and share your views.
The Basic Code for Calibration I used is from Examples of BSEC library:
