BME688 connection to Android App

[Minhwan]

Hello Livnov_Vitaliy, 

Thanks for sharing your info. 

It seems like there is some version compability issue with latest version , so if the comfie file is working, please use it now 🙂 

Thanks,

Please try below steps. ( I tested it again today)

• Download all latest software
  1. BME688 Dev kit Software (v.1.5.0)
  2. BME688 Dev Android App (v.1.1.3)
  3. AI studio (v1.6.0)

• Update firmware for BME688 dev kit based on 1.a
• Gather new data after reset BME688 dev kit (At least, two type of data you need)
• Run AI studio and learn algorithm, them generate config file. Then, generate BME board configure file.
• Remove previous bmeconfig and config files in SD card, and copy the files into SD card.
• Run Android app and connect BME688 dev kit

Just in case, I attached my test files.

Thank you.

Hello,

I have the same issue. 

How do you Update firmware for BME688 dev kit based on 1.a ? Is it via arduino or other method, I couldn't find a clear documentation so far? 

Thanks for your help

I followed EspressIf's esp32 documentation:

https://docs.espressif.com/projects/esp-ids/en/latest/esp32/get-started/

This left me with a command prompt window where I could flash and file to the esp32-wroom-32e adafruit feather.

I also setup an Arduino IDE but that took a lot of space.

on RPI4 it led to these instructions:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git wget flex bison gperf python3 python3-pip python3-setuptools cmake ninja-build ccache libffi-dev libssl-dev dfu-util libusb-1.0-0
mkdir -p ~/esp
cd ~/esp
git clone --recursive https://github.com/espressif/esp-idf.git
cd ~/esp/esp-idf
python -m pip install --upgrade pip
. ~/.profile
get_idf
./install.sh esp32,esp32c2,esp32c3

 Then esptool.py is available to perform the flash. I did:

. .profile
get_idf
esptool --port /dev/ttyUSB0 .........

From looking at the files, the test files weren't needed.

Thanks! I haven't proceeded to this point since my confidence levels of actually detecting coffee were pretty low.

I only purchased a shuttle board since I already have some esp32-wroom-32e adafruit feather boards. 

I believe I might have not performed the burnin period correctly. I flashed their firmware and just let it blink for a day.

There's some reading for me to do before I actually have any clue what is really going on.
