That's very interesting. When this happens, do you have it charging from USB? If so, when updating firmware, which version are you updating it to? (Tools->Diagnostics->Show Diagnostic Information) Have you tried the firmware update included with EScribe Service Pack 69 yet, or are you running an earlier EScribe (Help->About)? Also, have you tried a hardware reboot on the device? (Remove the pod and disconnect from USB. Then hold the Fire button until it reboots. It should take about 10-15 seconds.) Thanks! God bless. James

SP69 adds trace recording (showing the actual puff waveforms... well, a 8 Hz version of them). If you sync your puffs with ECigStats, what do you get for the puffs that say Fill Pod? Could you click "Download Puff" for the particular puffs and attach the CSV files here? Thanks!

@John R: Thanks! I've fixed it.

I've posted SP69. It corrects one possible cause of Fill Pod messages on Oxva Pro 2 DNA, which could occur if Replay is activated on the first puff after connecting a pod. It also adds puff trace recording support. This records Power, Live Ohms, and Battery Voltage for puffs sent to ECigStats, so, you no longer have to be connected to USB to see your puff trace. Let me know how it works for you. Enjoy

This version also adds puff trace recording to Oxva. You can view puff traces on ECigStats. It records Power, Live Ohms, and Battery Voltage. (We're hoping to use this recording to see how effective the Fill Pod change is. That said, it's also a nice feature -- you don't have to be connected to USB any more to get a recording of your puffs!) Definitely let us know how it works for you!

This was my concern about porting to GTK 3. The C# bindings have been in beta forever (effectively abandonware), so each distribution is likely to have a different version with different functions. Give this a try: https://downloads.evolvapor.com/SetupEScribe2_SP69_INT.run I changed how I register for the monitors changed event. I'll bet you'll have some other error, but it should take care of that one. My version of GTK Sharp 3, on Mint, is 2.99.3-4. What does it list as your version? Also, what's the specific OS version, etc.? I've not used Arch Linux before, but certainly could give it a try in a virtual machine. Thanks! God bless. James

I've ported Linux EScribe SP68 from GTK 2 to GTK 3. Some newer systems didn't have gtk-sharp2 easily available, so this should make those systems usable. *This is still a test version*, but if you'd like to try it, let me know what bugs you run into! https://downloads.evolvapor.com/SetupEScribe2_SP68_INT_GTK_Test1.run The bugs I've found so far are: (1) Multiline labels such as in Atomizer Analyzer don't lay out correctly. (2) Text fields with escape codes (such as Format and Label on Small Screen Pod devices) don't save properly. (3) Occasionally, dialog boxes are misaligned relative to the window that is showing them. Enjoy God bless. James

By any chance, is there a contact pin on your Oxva that is stuck down? We saw that once -- it caused poor electrical contact -- and because the electrical current is higher on the Stainless pods, the power losses from poor electrical contact are higher.

That's only 19% over cold, so it shouldn't be hitting any limits. I see you're using 1W extra -- do you find the coils taste about the same at that level? You still have headroom to increase it if need be.

Would you mind checking Cold Ohms and Live Ohms as well for the recording? It only has Power right now, from which I can't make a huge number of conclusions. (It only records the columns you have checked in Device Monitor, plus time.) Is your Power Setpoint 18 in all of these? (It's not recorded.) I do notice in the "Worst Mod" cases, the power is clearly declining, which suggests it is hitting a limit of some kind, but hard to tell only from that. What will be interesting to see is what the percentage difference is from Cold Ohms to Live Ohms in the "Good" case. That'd tell you how close you are to the "edge" (24% for the Stainless coils at current presets). Thanks!

I've posted SP68. It improves the battery meter accuracy and stability on Oxva Pro 2 DNA. (For Oxva Pro 2 DNA, it also adds Battery Capacity and Battery Cycles tracking to Device Monitor. After each full charge/discharge cycle these will update.)

I've posted SP68 for Linux, which gives the Oxva Pro 2 DNA a more accurate battery meter and some charge state estimation support.

@franticseven, the device is set to turn off automatically if idle for 130,000 seconds (about a day and a half). It doesn't have to be awakened by USB -- holding the fire button for a few seconds wakes it up again. The device has pretty decent idle current before it turns off, and so should not drain more than a few percent during this time, whether or not the pod is connected. It should remember Replay coming out of idle but not turn-off, unless something has caused the pod to lose contact during that time. It looks like your power output is actually higher on the Stainless coil. What does the trace look like in Device Monitor with the Stainless coil when puffing, Power and Live Ohms? It looks like you're rising about 21% on puffs, so it shouldn't be hitting a limit.

Hmm. I think we just did it because it didn't fit on the screen. Do you need fractional wattage at 10W and above, or would below that do the job? Is this for ordinary vaping (a perceptible difference etc.), or is this for some research-related use? Thanks! God bless. James

The USB charger chip we are using on the Oxva Pro 2 DNA has a "system reset" feature which is specified to activate at nominal 12.5 seconds of button press (by specification, between 9 and 14.5 seconds). This is handy in case your device locks up, but it does mean we actually can't extend the puff time much in software. Had we made it (say) 10 seconds, there'd be some fraction of devices out there that would reset before they got to the end of their puffs. Sorry about this. If you don't mind me asking, do you vape very long puffs or is this a special or research use case? Thanks! God bless. James

Hello, Would you mind posting a screenshot of Device Monitor when taking a puff, or posting a recording CSV of the puff? I'd be interested to see what Power is doing, and what the Live Ohms are. Make sure to check those. You can click on the trace as it scrolls to get the values at a particular moment in time. Your screenshot also shows Cold Ohms as 0, which indicates it hasn't fired yet I assume. What do you measure for Cold Ohms for the coil? I'm curious to see what limit you are running into. Thanks! James

Here's a question. If you pull up your puffs in ECigStats, is it saying "dry coil"? What do you get as your Cold Ohms and Live Ohms near the end of your puff? I'm wondering if Live Ohms is 18% above Cold Ohms (dry coil) or 24% above Cold Ohms (wet coil)? It determines wet coil by how much energy can go into it in a quick amount of time. If a juice is particularly bad at wicking, that could be the cause. I think John tested with 50/50 VG/PG, but I'm not sure. I will ask him next time I talk with him. If a juice has a ton of flavoring, enough to meaningfully affect the thermodynamics, I wonder if that could cause it. Let me know about the Cold Ohms and Live Ohms. We have a ton of settings on these devices, so none of this is hopeless or set in stone. Equivalent Ohms is something of a practical compromise. People tend to associate the vape they get with a Kanthal coil of a particular resistance. But what they are really asking for is not an electrical resistance, but the thermodynamic properties associated with that electrical resistance. The resistance of a Stainless coil, for the *same surface area and other thermodynamic properties*, is different from a Kanthal coil. Thermodynamics doesn't care at all about electrical properties. So, if manufactured correctly, a Stainless coil of "Equivalent Ohms" is meant to match the *thermodynamic properties* of a Kanthal coil of a particular resistance. Now, one could do it another way, but otherwise "I want a vape similar to my 0.6 Ohm Kanthal coil, but with temperature protections" becomes a rather confusing question to answer. Hope this helps. God bless. James P.S. There are other practical compromises. See the "True RMS Power Mode" checkbox? That's a fun one. If you want your watts setting to match your expectation on every PWM pod device we saw, keep it unchecked. This is "PWM Power Mode". If you want your watts setting to match thermodynamics (and non-PWM devices), check that checkbox! This is "True RMS Power Mode". (Actually, we did do better than other PWM pod devices when in "PWM Power Mode". See "Simulated Battery Voltage"? We make the true thermodynamic watts setpoint stable with battery voltage and battery voltage drop. The way most devices do it, this isn't true. Read on if you care about the math.) It turns out all of the PWM pod devices determine their duty by P=Vpod^2/R, so Vpod=sqrt(P*R), from which they conclude PWM=Vpod/Vbat=sqrt(P*R)/Vbat. A multimeter will back them up in this. (Mostly. There's also a huge battery voltage drop when firing on PWM devices.) The voltage is correct! Unfortunately, this is wrong. A multimeter will average the voltage over its sampling period. A PWM device is actually on/off. So the *real* power on a PWM device, when fully on, is P=Vbat^2/R, because it is connecting the battery to the coil. So, at a particular PWM duty cycle (0-1), you get P=(Vbat^2/R)*PWM, or PWM=P*R/Vbat^2. What's humorous about this is, when you measure with a multimeter, you're going to see the *averaged* voltage Vpod=PWM*Vbat=Psetting*R/Vbat. You're going to say "Let's use Ohm's Law", Pcalculated=V^2/R, and apply it to that averaged voltage, to get Pcalculated=Psetting^2*R^2/(Vbat^2*R)=Psetting*(Psetting*R/Vbat^2). See? The multimeter will tell you that it's wrong, when it's thermodynamically correct. You can't average voltage and then do that calculation on a PWM device. The factor by which it's off is how wrong the other calculation is. What you can see from the equation is that the way other PWM pod devices calculate wattage is not only incorrect, but the real wattage will change as the battery drains, and in a way that is different depending on the coil resistance. Fun! This is why the Oxva Pro 2 DNA has a "PWM Power Mode" Simulated Battery Voltage setting. We did better than the other devices by (1) matching the wattage you'd find on other PWM pod devices, *at near full battery*, while (2) using *correct* power control to make that stable over resistance and battery level. We left both options in. We knew for "PWM Power Mode" that most users of pod devices would be surprised if, even if entirely correct, the wattage level they set felt different than other devices. We also knew for "True RMS Power Mode" that we have some folks who can appreciate an accurate and correct vape.

Try going to Tools -> Diagnostics -> Reboot Device -> Hard Reboot. Does this fix it? Thanks!
