The saga continues apparently. I just received the brand spankin new S2+ with the SST20 and it’s got the super fast strobe and mode select going on. I got a C8+ as well, and it works at the correct speed. I’m not going to try enabling memory mode on the new S2+, because knowing my luck, It’ll get stuck there.
I contacted simon, expressing my annoyance that lights with a known issue are still being shipped. I’ll update if he replies.
I kind of wanted a OP reflector version of the S2+ as well, but I don’t really want to risk getting another weird one. I’ve been kicking around the idea of buying all the parts from MTN and building one with one of their guppydrv drivers instead.
Yes my S2+ with SST20 which arrived a week ago seems to have the faster flashing firmware aswell.
These days I try not to change modes too often, and am very cautious about accidentally pressing switch through the second “buzz” for fear of memory ‘jamming’ another driver.
I will still buy from Convoy and support Simon but the drivers are definitely the weak link in these lights.
I don’t really care about the speed. My issue is that, according to ToyKeeper, the speed may be an indicator that the memory bug exists.
I worry I may click on the second flash rather than the first when changing groups and trigger memory mode by mistake, which seems even more likely given the speed at which the flashes occur on the “overclocked” driver.
The reckless part of me wants to just enable memory mode and see if it has the bug or not, so I’d know for sure. The slightly more rational part says don’t do it, because then if it is broken I’d have to hassle with trying to get a refund or replacement through aliexpress/simon.
Simon replied that he’d send me a new driver if mine was defective. So I went ahead and tried enabling and disabling memory mode a couple times. Turns out it works fine.
If you are in the US I can send ya a OP reflector for the S2+. I have more than a few laying around. Also have some waffle type 60 degree TIR’s as well. Very nice floody beam. PM me with a address if you would like one or two.
Thanks for the offer, but I think I’m going to leave this one as is, as it does have a pretty nice beam. I want to try my hand at building one, so when I do that I’ll order a host that includes an OP reflector. So I’ll have this throwier one and a floodier one.
:edit:
Actually, maybe I would like to have it to play around with. I’ll pm you.
Yes, the issues are pretty random. It depends on the state some individual bits of RAM decay to when power is removed. Basically, the batch the driver is from seems to determine the odds of having a problem, but it is not a certainty. Issues didn’t show up in any pre-production drivers, but only a few were actually tested.
Unfortunately, that wasn’t the only issue. For example, the production drivers were a different design from a different manufacturer, so the firmware was calibrated for the wrong hardware.
just receiving my 2 convoy S2+ ordered in mid April ( one with SST20 & one with Nichia) and unfortunately i got the same problem (all of them). i cannot turn off the memory mode. this is annoying.
i already try to contact simon the seller, and i still wait for his reply.
I bought 3 of these SST20 S2+ with biscotti, just because they were so good VFM; I have only powered one up so far and on a slightly different note to this thread and in the absence of finding the information anywhere else - I went into programming mode to change the mode spacing, which worked without error. Unfortunately I programmed the wrong mode in error, so went back into programming mode and changed the mode again; fortunately I got it right this time as I can no longer get into programming mode to change anything - is this a common failure mode and is there anything that can be done to fix it, or is it a good excuse to try and learn processes for reflashing I if one of my batch has failed this way, are my other 2 likely to go the same way?
I’m not concerned about the apparent failure, as it’s failed stuck in a mode I want and they were dirt cheap anyway and I can use them as triple hosts, I was just curious if it’s recoverable or if I’d need to reflash the MCU/replace driver to restore full functionality.
hello everyone, even though i have boungt the new convoy c8 plus, my old convoy c8 clear suffers from the problem of not be able to change mode. i use the 10 times tap but the only thing that happens is that sometimes it changes the power of the light 100% or something like 30%. Is there somethong i can do to fix this beautiful thrower? i don’t hve acces to programming tools and stuff. Thank you in advance.
Concerning the above Biscotti instructions crib sheet, with mode memory on it reads “enter into next mode”. Seriously? The dreaded next mode memory? Wouldn't it make a lot more sense if it were “enter into current/last used mode”?
