I can fire the flash standalone or by pressing the test button on the flextt5 while the flash is on it.
The red led on the flextt5 flash 4 times when I press test on the minitt1 or press the shutter on the camera when connected to the minitt1.
So flash works, minitt1 to flextt5 radio communication are working. Why is the flash not firing???
This has worked before. I have tried new firmware downloads and resets of both units but no more luck.
