I was waiting for your kind reply on how to synchronise the godox x1r x1t & canon speedlite 430exii.. Thank you
When we have similar questions here, it's almost always the same thing.
I'm going out on a limb here and assume you have the transmitter properly attached to the camera's hot shoe with on-camera flash enabled in the camera's menu. As far as the camera is concerned, the X1T is the flash.
I'm also going to assume you have the 430EX II properly attached to the Godex receiver with the flash not set to slave mode. As far as the flash is concerned, the X1R is the camera.
We'll also assume both the X1T and X1R are both set to the same channel and group.
What else could it be?
In addition to Group and Channel, the newer Godox/Flashpoint transmitters and receivers (both internal and external) have the ability to designate an ID number of 1-99 (plus "Off"). The older pieces of the system do not have the ability to use ID numbers. In order to use the older pieces with the newer ones, the ID number setting needs to be "Off" on the newer units. Even with the newer units, the ID numbers that are set on each unit must match each other or the other unit will ignore it.
