I2C works but can't scan and find address


Redbear BLE Nano2 / DAPLINK1.5
Arduino 1.8.5
Sparkfun 9dof sensor stick (LSM91DS)
Oled generic i2c as found on net.

I can hook up an OLED over I2C and everything works properly. But I want to hook up a LSM9DAM 9DoF sensor over I2C and need to establish address (mag and gyro/accl). It hangs in setup and never goes to loop.

I cant even get the I2C scanner code to return a valid address. If I implement Wire.begin (); in setup it will return 126 address found. If I leave Wire.degin out it just says scanning and does not return no devices found.

Is there something simple I’m missing???
