No display on SSD1306 display device at all. No clue why. Jeston Nano B01 Jetpack 4.4 latest ubuntu-python etc upgrades.

All wires are just plugged in with the supplied harness. Nano powers on fine. I installed with setup.py, install.sh does not complete, no error given. I used the commands in install.sh successfully. Service appears to be started. I can run python3 -m ups_display.ina219 and see the stats supplied correctly. I use i2cdetect and see the device plugged in at bus 1 0x3C+0x42. I used a script to test the display with just a simple read out and was successful. The device works. Nothing else on that bus or any other i2c. Again, no errors., just no display. Clueless unless you guys can show me a working model. Has this been tested??? Spending a lot of time beta testing an expensive battery charger.
