Bltouch blinking red on Duet wifi+ Duex5 RRF 3

@DIY-O-Sphere yes it does, I also looked at other troubleshooting and bypassed all cabling connecting the bltouch directly with short cables and the behaviour is the same:

Performs well the initial self test
Performs well the M401 (fixed blue light)
performs well the M402 (fixed red light)

but when I try to home or to manually trigger the bltouch start to blink red

all this test were done with two original BLTouch v3.1 one of them was connected to an already perfectly working cartesian printer

Can you confirm that the white wire from the BLtouch is extended all the way to the zprobe.in pin?

@Phaedrux yes if you look at posted pictures the white cable is connected to the duet wifi probe connector as green cable. Basically the white is on the GND and the black is on the probe.
Should I invert them?

No, the white wire should be connected to the Zprobe in pin.

You can try removing the ^ from C"^zprobe.in"

@Phaedrux too late... I inverted them and (believe me I don't know why cause white is connected to the green) but finally it does home!!!!

it works... I'd like to thank you and this fantastic community of very kind and helpful 3D printing lovers and professionals

Then I suspect there is a crossed wire somewhere.
