No pull up found on SDA or SCL; check your wiring No I2C dev

Yup.

OK. Thanks. Really weird. It seems like a connection issue. Try removing the motor and speaker wires connected to the Crickit just to get them out of the setup for now. Then go over the bolts again. Maybe even try just removing them all and reattaching them. See if maybe they just need to "seat" better? You can check with the I2C scan test from REPL.

I unscrewed the whole thing and put it back together and tightened the screws/bolts. Ran the i2c scan test in the REPL. Same thing. It returned an empty list.

OK, let's go ahead and try updating the Crickit firmware just to see if that helps at all. Try the process outlined here:

and then try the scan again.

Carter,
I put on the new Circuit Python 7 the other day and decided to run a GPS program for fun. After updating all of my .mpy files, I had this same strange problem. So I did what you suggested in this post, and unplugged my lipo battery as well. It worked perfectly. Now I am sitting here amazed at how old that code is...

I am using a Feather M4 express, the 128 x 64 oled feather, and an i2c connected GPS. All adafruit.
The text seems much brighter???
No reply is needed. Thanks for that suggestion.
