Hi James I'm using the latest firmware available : 2015-09-30 with the software 1.0.34. Next time the problem happen i will try to capture those information ! Yesterday, thinking that the problem was the connectivity between the dna and the 510 i resoldered the wire .. so maybe the problem was from here because for now that's working fine.
After some more tests, look like this is happening when the resistance become smaller instead of becoming bigger like this is supposed to happen. I'm using only 316L for temp control. For sure i never got this problem with my first unit. And i was using the same atomizer.
I just received a new dna200 from warranty and he is working fine, most of the time. I just got a very strange bug sometimes .. When i push the button the dna give the boost power and never stop, when that happen i can see on the screen 3554C .. My boost is configured for 1sec only so i really dont understand why he dont stop after that time. To stop it doing that i have to lower the temperature setting.
Some people will try to protect Evolv saying that this is because the assembly is the problem ... but i agree, i also got one dead dna200. You just have to search inside this forum to see that there is a lot of problems with the dna200 for now. I got a lot of box and this is the first time a chipset is dead after one week :-/ For sure Evolv are working on this problem right now, but they dont want to admit ...
@Popeye : Someone on a french forum said that the battery on the Vtbox200 is 1220mah .. he measured that with a external charger. I also got the VTbox200 and i will try with something around 14Wh to see what happen For now i'm waiting for my new chipset because the first one is dead
I dont mean that there is no wire between Ground and 510, that was my question : do i need a good connection to ground even if 510 is connected to ground ? I ask that because when i look at the chipset, i cannot see a direct connection between differents ground .. so, is this better to make a good connection between the grounds ?
