can it run on ESP32? #3

Closed vfebert closed 4 years ago

vfebert commented 4 years ago

Hi, was really happy to find this one, intending to do a "My own CO2 footprint" project. Could you please help me in providing an Arduino example running on an ESP32 - which has Bluetooth build in. When I compile the sample sketch, it simply gives "serial3 unknown" error. Sorry for being only a hobby programmer....

big thanks to you for making it working perfectly now - My application based on your SW is up and running now also: "Visualize your daily CO2 footprint based on your car fuel consumption, heating, electricity, water"

Glad to help! Do you have a link to your project build?

vfebert commented 4 years ago

not yet - working on it - will keep you posted

Hi @PowerBroker2, thanks for all the hard work on the library. I'm using an ESP32 Dev kit with Bluetooth ELM327 module. I'm using your example & the connection goes through correctly, but all I get is ERROR 7, even after 3 minutes: image

Tried sending the AT commands with the basic sketch, it works fine. Any ideas ?

Thanks

Looks like you're getting a timeout error. So I can keep track of everyone's issues separately, please make a new issue describing your exact hardware setup, testing environment, library version, and complete code.

Sure, thanks!

Hi PowerBroker,

finally I can answer your question: „do you have a repository for your solution?“ – it was about the project to read out mileage and fuel consumption fully automated.

Here it is: https://myco2.org/

The repository is: https://github.com/VolkerMyCO2/CarMileageFuel

Hope you like it and everything is ok for you. If not, just let me know.

Regards,

Volker

You were able to connect to it via Bluetooth serial or did you have to modify the example for BLE? I'm interested only in how you were able to connect the ESP32 to the BLE OBD scanner (if that makes sense).
