Running this code (python) :
import u6
d = u6.U6()
d.configIO(NumberTimersEnabled=4)
d.debug = True
# Set FIO 2 to digital output
d.getFeedback(u6.BitDirWrite(2, 0))
# set FIO 2 to output low
d.getFeedback(u6.BitStateWrite(2, 1))
# Invert state (to 1)
state = d.getFeedback(u6.BitStateRead(2))
new_state = 0 if state[0] else 1
d.getFeedback(u6.BitStateWrite(2, new_state))
state_end = d.getFeedback(u6.BitStateRead(2))
print(f'{state}, {state_end}')
Yields the following output:

It seems like the BitStateWrite is not working for the FIO. What am I missing ?

I tried this as well... Same results.
import u6
c = u6.U6()
c.debug = True
c.setDIOState(2, 0)
print(c.getDIOState(2))

The state for FIO2 cannot be set since it is configured as a timer. This:
d.configIO(NumberTimersEnabled=4)
Configures FIO0-FIO3 as timers. If you disable timers (NumberTimersEnabled=0), or use the digital I/O after FIO3, you can configure the output state of the digital line and read back the expected state.
Also, note that the timer settings will be in effect until disabled by code or the device is power cycled, which is why you still see the issue in your second post.
