How to update Firmware on BME688 Development Kit

[Caiohachem]

Hello,

I am trying to update the firmware on the BME688 development kit in order to use it with the android app, but have been unable to find any instructions on how to do so. Can someone please help me with instructions on updating the BME688 firmware?

Thank you

Hi @Caiohachem  

There is BME688 dev kit sw in below url. (Current version is v2.0.9)

https://www.bosch-sensortec.com/software-tools/software/bme688-software/

You can update firmware using bat file in zip file. 

Thank you.

Could you give any instructions where to find those files and how to update them. I am not verry technolagically adept and a step by step instruction would really go a long way. Thank you.

Dear Minhwan

I have de dev kit which sends the following message upon pressing the reset button:

ets Jul 29 2019 12:21:46
rst:0x1 (POWERON_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

I have also the android app BME AI Studio v.2.4.19 

I have followed the downlink instructions to get the latest version of the dev kit software v2-1-4.

After unzipping the dev kit, I start the Flash and get the following message:

Enter COM port number (e.g. COM21)5
esptool.py v3.3
Serial port 5
Traceback (most recent call last):

serial.serialutil.SerialException: Cannot configure port, something went wrong. Original message: OSError(22, 'Falscher Parameter.', None, 87)
[6992] Failed to execute script 'esptool' due to unhandled exception!

1. Question: WHERE IS THE File "serial\serialwin32.py?
2. Question: WHERE IS THE bmeconfig file?

Please help me! st.jo.schmidt@gmail.com
Thank you !

I covered the flashing of the devkit and pre-reqs on the PC in my acticle on teaching your pi to sniff - https://github.com/mcalisterkm/teach-your-pi-to-sniff-with-bme688 

Follow the "README" by scrolling down  - Steps 1 to 4 are probably relevent, the rest are Raspberry Pi focussed. 

This was done using BSEC 2.4.0.0, so you will need to adapt when using BSEC 2.5.0.2.
