Nano 33 BLE pull-up resistors on i2c

Nano 33 ble (non-sense) external i2c scan isn't working

I've found the aug 2020 and the oct 2019 posts. And for me the scan program from oct 19 only sees internal i2c addresses, 0x1E & 0x6B, I know about the IMU, not sure what the other one is. This scan and and the original and the aug 2020 scan do not see my i2c device, which is a TSY01 temp sensor at 0x77 external, which works fine on a nano. Using arduino ide 1.8.16 I've found nothing else searching around. I'd like to get the i2c scan working first. Thanks for any suggestions, perhaps…
