Hi Teseo liv3F on I2C sometime stall (and on UART too), i ask for a report each second, randomly about each minute i2C tx stop for 2 to 10 seconds (sometime more) and resume.

I suspect a low power setting.

Tested on STM32F746Disco and on Arduino https://github.com/stm32duino/X-NUCLEO-GNSS1A1.

Seem to be the STAGPS bit 4 in CDB200 should be set.
