WipperSnipper ESP32-S2 doesn't see BME280 onboard

Post by kise1_off »

Hello!

I just bought a Feather ESP32-S2 with onboard BME280.
I tested the board with Circuit Python and Arduino IDE. The sensor is located at address 0x77.
When I am trying to start the I2C scanner on WipperSnipper, the scanner can not find anything.

I tried to initialize VSENS pin on D7 in WipperSnipper, and start the WiFi scan with toggled D7 pin ON and OFF.

It will be awesome if you can help me with this problem.
Thanks!

I know they changed the i2c bus power on the rev B and rev C of the Feather ESP32-S2 with BME280 & without BME280.

And I believe there are some fixes in Circuitpython around that as well.

Perhaps the Wippersnapper firmware is lagging behind that?

Check the release notes.

Ok, I just installed wippersnapper onto my Feather ESP32-S2 with BME280, and it doesn't detect anything on the Stemma/QT connector, either.

There is an existing "issue" report for wippersnapper to add i2c initialization support for the rev B and rev C of this board.

https://github.com/adafruit/Adafruit_Wi ... issues/239

So it's just a matter of support lagging for a new board design.

I just learned from you that this "issue" page on GitHub exist.

So, I will wait until the new update of WipperSnapper will be released.
Thanks!

Hi, this will be fixed and released with beta.30 sometime next week. I will update this thread when we've released beta 30. Thank you for the report and your patience.

I am not the Original Poster, however I have tested beta.30 for the Feather ESP32-S2 with TFT, without TFT but with BME280, and without TFT and without BME280 and it worked on all three.

Just an FYI for the OP and Adafruit support.
