I have used the Canon ST-E3-RT (version 1) trigger with the 430 EX III-RT and 600EX-RT (version 1) flashes for off camera flash for several years. Previously they worked flawlessly but now the signal gets dropped within a minute of switching everything on. The units are all on the same channel and have the same ID with fresh batteries. The only way to re-establish connection is to turn everything off and then on again. Unfortunately, the signal will again drop after another minute or so. This happens when I use the 430 EX III-RT to trigger another 430 EX III-RT or if I use the 600 EX RT to trigger the 430 EX III RT units or if I use the ST-E3-RT to trigger the flashes (one at a time or all three flashes together)
The flashes are within 5 feet of each other with no intervening barriers such as a wall.
This has happened to me indoors and outdoors, at several different locations.
I used a friend's Godox trigger/receivers at some of the same locations and they worked flawlessly.
Several others have mentioned this in various forums and suggested that there could be interference from wifi systems or even LED lights. To test this, I turned off my wifi and then all electricity to my house. Unfortunately, the problem persisted.
I contacted Canon and their response was to say that they are "aware of the problem but have no solution".
Has anyone else encountered this and, if so, what solution do you suggest? Spend more money on another trigger system (seems counterintuitive since this system was created for off camera flash), sell Canon flash and buy "knock off" versions?
Any help would be much appreciated.
