Send a serial command. F=60S will do a 1-minute puff, for example. On monochrome DNAs, F=#S (# being the number of seconds) sets a countdown timer. So, while it is firing, you can keep sending F=60S to extend the puff. F=0S stops the puff immediately.

Yes, the debug setting doesn't retain after power-off. It looks like the steady state power is different slightly. Am I seeing that correctly? Also, could you try an in-between value such as 0.04?

Howdy @ndb. Give this firmware a try. I think the issue is current offset when it's down at 0.5W. In Serial Terminal, X=GET COB gets the current offset. It is 0.025 by default on DNA 75 Color. On a DNA 75, it is 0.0625. Try X=0.0625 COB and see if it fixes the oscillation. I suspect it will. Thanks! DNA 75 Color v1_1_SP22_Beta2p2.sw-service

OK. Well that rules out X=READ DEBUG being the problem. Out of curiosity, what power level is it dropping to there? (To get to the recording, go to Device Monitor -> History -> Download All Recordings). It looks like a current offset issue, to be honest.

@ndb, if you go to Tools->Serial Terminal after having it pulsing like that, what does it say if you send the command X=READ DEBUG? Thanks! Also, for the rest of the folks trying that firmware, I'd be real curious what you get for that value after a while of normal use. (Sending the command resets it for the next time it's sent. No need to measure it every puff. I am wondering after a session what it is.) I'm expecting around -0.14 for temperature-protected coils, much less for Kanthal.

The attached beta firmware fixes the loss of Room Temperature modeling after uploading settings. Since folks tend to edit settings when things go wrong, this should mean a lot less incorrect 90F measurements. DNA 75 Color v1_1_SP22_Beta2.sw-service

With that firmware, you should certainly use a normal TCR like you would on a DNA 75. What are the board temperatures doing while the room temperatures are measuring like that, out of curiosity? Personally, I would try our default case thermals. I'm actually fairly skeptical of the DNA 75 Color Case Analyzer as it is implemented in the current Service Pack. In my opinion, its numbers are unreasonably high, and incorrectly aggressive thermals can definitely do what you are seeing. When I get time, I am going to investigate that. FWIW, if I am reading what you are doing right, you should know: when you measure Cold Ohms, it automatically takes Cold Temperature from Room Temperature. You don't need to do that manually.

You can get the most recent firmware for your DNA 75 Color by downloading EScribe Suite 2.0, from https://www.evolvapor.com/products/dna75color Alternatively, here are the links: EScribe Suite 2.0 US Edition EScribe Suite 2.0 International Edition Once you install it and connect your device, if you are not running the newest firmware, it will offer it.

If you are feeling adventurous, try the attached firmware (Tools -> Apply Service Pack) and see if it helps your Cold Ohms measurement. DNA 75 Color v1_1_SP22_Beta1.sw-service

It's a very good idea. The most recent version has a number of bug fixes, some of which are important. Download EScribe Suite 2.0 from the DNA 75 Color page, and it'll offer the firmware when you connect (near the top of the screen).

The board should retain the clock for about 30 seconds after a battery is removed, so that it won't lose the clock for a quick battery swap. Hmm. What is the battery voltage reading? Does it start charging again if you go to Diagnostics -> Disable Charging and then Enable Charging?

Hi @ndb. Mod resistance... When you measured with a copper plug and Atomizer Analyzer, did you have your mod resistance set to 0? The measurement you get there incorporates the current mod resistance setting (for example, if the whole mod resistance is 0.016 and your mod resistance is already set to 0.004, it will read 0.012). I need to make it show the raw resistance as well, for mod resistance use. With your 0.800, does it stay fairly consistently near there in Atomizer Analyzer? Or does it bounce around? (I am wondering if certain resistance ranges are less consistent on their cold ohms measurement, and/or if there is a grounding issue.)

Hello @ndb! This has been fixed in the newest Service Pack.

Hello @eucalyptus.! This has been fixed in the newest Service Pack.

The underlying code already works on Mac and Linux, actually (the Downloads section's theme previews are being generated by EScribe running command-line on Linux, for example), but the graphical interface needs to be ported over. As of today I've converted the last screen from Microsoft Windows Forms to our platform independent windowing layer. I work on it when I need a break from other code, so don't hold your breath, but I have been making progress.

Hi @gogo. I've updated the theme previews to show all screens. Hope it helps you. James

Spot on, it's an EScribe bug with odd numbered profiles. Looks like a remnant from something we were testing a while ago. This should be an easy fix. Thanks! By the way, I notice that Ohms in Atomizer Analyzer doesn't use a comma (the separator for your locale). Definitely let us know if you run into localization issues like that.

We've found the bug. It was theme related, and will be fixed in SP21. Thanks Andersen for finding it!

The Cold Temperature is the estimated room temperature when the Cold Ohms were acquired, yes. It may not be a perfect estimate, but as long as it's pretty good, you should be fine. By splitting Cold Ohms into two values in this way, instead of storing a 70F Cold Ohms, a Theme can have a Material selection (separate from Profile) and let Material be changed *after* sampling Ohms. The current themes don't do this, but the option is there. If it does not update, it might be having an error sampling. Does Atomizer Analyzer show ? on those profiles instead of an Ohms? If so, please send me your .ecig settings and I will investigate.

This is a firmware bug. Looking at the code, if your theme uploaded correctly but something about the theme makes the firmware crash or freeze, the Error Press Up screen might not wait for a button press. Tomorrow I will message you a custom firmware to try.

Interesting! "Error Press Up" seems to go away very fast. Are you pressing Up? If so, instead of pressing Up, could you download the settings when it is at that screen, and send me them? It looks like it is crashing. I'd like to find out what settings could cause that. Also, what Service Pack are you running?

Hmm. If you get the message "The firmware is starting, it may take a moment." the screen should come on in about 1 minute. That happens if the firmware had crashed. Alternatively, you can get it to start immediately with Tools -> Diagnostics -> Reboot Device -> Hard Reboot. Does the screen appear white (no text) after this, or does it show something else? Could you take a video of what it is doing?

For those interested, I've created a C# (.NET) client library for the ECigStats API. https://forum.ecigstats.org/viewtopic.php?f=3&t=24 Enjoy James

Is the resistance consistently wrong in Atomizer Analyzer? If so, definitely make sure your case grounding is good (are the grounding screws loose?). The measurements used to sample Ohms (for Atomizer Analyzer or New Coil) are done at very low power (otherwise the atomizer would heat up while measuring, which would ruin the measurement), so grounding issues can be more significant than at full power. This is true for other DNAs as well, incidentally.
