impOS36 - thermistor readings


#1

Hi all,
Not sure if this has already been asked, I did a quick scan, but didn’t find anything…
I received an email from imp saying that the OS systems have been upgraded. I have two IMP001 cards taking temperature readings and posting them to the net.
I couldn’t find anywhere on IDE site that would tell me what version of the OS is installed on my devices and when it was installed, so I can only assume that my current problems are somewhat/somehow related.
Both of my devices jumped approx 2.5degs at the same time and are now reading consistently higher than the ambient temperatures.
Not sure how an OS update could affect the readings continuously. I could understand a temporary temp increase due to activity but I would expect this to reduce over 1/2 hour or so.
The change occurred at midnight 8th June local time, or 2pm on the 7th June Z time.
I have attached a jpeg of the graph that shows the jump at this time.

Any thoughts anyone? (I am rather new at this… so some patience with me would be appreciated)

First, you can see what’s changed with the new impOS release here: https://electricimp.com/docs/releasenotes/releases/release36/

You can use imp.getsoftwareversion() to determine which version a given device is running. For example, I add the following to all my development code and call it early:

function bootMessage() {
    local a = split(imp.getsoftwareversion(), "-");
    server.log("impOS version " + a[2]);
    local i = imp.net.info();
    local w = i.interface[i.active];
    local s = ("connectedssid" in w) ? w.connectedssid : w.ssid;
    local t = (w.type == "wifi") ? "Connected by WiFi on SSID \"" + s + "\"" : "Ethernet";
    server.log(t + " with IP address " + i.ipv4.address);
}

Nice Imp power-up message someone wrote

Also, please could you let us know the MAC address of your imp? We can then look up when it upgraded.

Hi Harry,
Thanks for looking into this.
I recorded the device id at time of installation as 230e9eab5ba5ceee and 23555aaa5ba5ceee, not what I would normally call MAC addresses, but then I am fairly new to this, so I hope this is what you after.

Both devices exhibited the jump in temp at the same time, which is why I presumed it may be related to OS upgrade… perhaps…

I did try to find the MAC addresses under my router, but it doesn’t show names of devices for all devices, but then I tried a MAC address converter and found two that have an OUI that came up as electric imp.incorporated… so the MAC addresses are;
0c:2a:69:05:04:53
and
0c:2a:69:05:04:45
Thanks for your help.

Hi Smitty,
Thanks for the code.
I presume this goes into the device code segment?..
I’ll give this a go and see what I get.


#6

That’s right - just drop it into your device code.


#7

Your devices are running impOS 36.7.

Can you tell us more about the thermistor hardware you’re using? Is it part of an Explorer kit, or a component you’ve connected to one of the imp’s peripherals yourself?

Also - an obvious thing, but if your is device is battery powered, please check the batteries are OK.

Hi keithfr,

Myself and Harry just did a test with a Imp Explorer Kit running 34.11 then which we upgraded to 36.7 the device was being powered by a USB cable. We ran this to verify that did not see any no sudden jumps in temperature output after a upgrade due to something up with the OS or after a cold boot. See the output.log and device.nut and agent.nut for the code and output we saw in the attached zip file.

Hope this helps and is useful,

James

Here is the logs saving people downloading and unpacking the zip. From what myself and harry could see we could not spot anything out of the ordinary.

Hi Harry,
Thanks for checking this for me.
The Imps are on a breakout board from Sparkfun, with thermistor, resistor and capacitor soldered directly to the breakout board and then connected to a 9volt battery. The program sleeps for 15mins, wakes, takes a reading, posts the results and then goes back to sleep.
I followed this instructable…


Can you tell me when and what time the OS updated on the imp?
From the directions we expect to get about 18 months from a 9v battery, also I have two temp sensors running and both exhibited the temp jump at the identical time, which would be highly unlikely if it was battery related. But I can easily replace one battery, the other is in the roof and so is a bit harder, so I’ll check this later today.

Hi James,
Thanks for the effort to replicate the issue.
I am not saying that the OS upgrade caused the issue, only it looks that way… If I only had the one IMP I would be checking components, battery, etc and changing the calibration to get the temp back to where it belongs, but when both jumped at the same time it just seams odd…
My IMP’s are only for my information and so the actual temp is not really that important at the moment. Although I would prefer them to be close and I would like them to be able to control air movements in my house at a later date… something to aim for…
I have bought another 6 imps and breakout boards as I wish to extend the monitoring to more rooms. If I set these up will they upgrade straight away or will it take some time to propagate through the system?.
Thanks for a great product.
I’ll have to check out that explorer kit… :slight_smile:

Hi Keith,

Thanks for supplying this extra information about your project. It’s an analogue design very different to the impExplorer so our quick test yesterday wasn’t very comparable.

The imps did upgrade around the time you saw the temperature increase (1.45pm and 2pm on 7 June Z-time), so you’re quite justified in suspecting a connection between the two events.

It’s hard for me to see how they could be connected to the firmware changes, or the upgrade process. But this doesn’t mean it’s impossible. I’m going to ask my team for some ideas.

In the meantime, there is a simple test we could do to confirm a link to the firmware upgrade: we can downgrade your imps back to 34.11 and see if the temperature readings revert. Let me know (on IM) if you want me to set this up.


#13

I have bought another 6 imps and breakout boards as I wish to extend the monitoring to more rooms. If I set these up will they upgrade straight away or will it take some time to propagate through the system?

Since impOS 36.7 is now the default for developer imps, your 6 new imps will probably upgrade to this version as soon as you power them up and connect them.


#14

Thanks Harry,

I’ll see how your test goes, and then I’ll have to get my hands dirty on some coding…to get the calibration closer… mmm
It has been many years since I used FORTRAN… doh… (I was rather good at back in my day…but a lot has changed since then…)


#15

I’ve tried a test which more closely replicates your setup - repeatedly measuring ADC readings on a fixed external voltage of about 1.6V, while switching an imp between impOS34.11 and impOS 36.7. I can’t see any measurement offset between the two firmware versions. This log shows (on the right) the impOS version and raw ADC measurement on one of the imp001 pins.

Hi again,

So … our experiment with downgrading your imps had the result that the reported temperature measurements dropped again, which seems to support the connection with firmware version, and certainly wasn’t the result I expected.

However, a colleague from the imp team has a theory why you’re seeing these results:

This project causes the imp to regularly wake up, connect to our servers and make a measurement via its ADC and the thermistor. But in a battery powered device, the reference voltage against which the ADC is calibrated may fluctuate a little during the time the imp is waking up and reconnecting, due to background activity particularly by the WiFi radio. This nature of this fluctuation is probably quite repeatable for a given firmware version, but might vary a little between firmware versions, which could explain the offsets you’re seeing between 34.11 and 36.7.

The way to test (and potentially fix) this in Squirrel is to introduce a delay between switching on WiFi and making the measurement. See the documentation for server.connect() and server.disconnect().

An easier check could be simply to increase the amount of data points in your measurement e.g. via

myThermistor <- thermistor(temp_sns, b_therm, t0_therm, 100, false); // Increase points from 10 to 100.

If these changes affect your readings, without a firmware upgrade, we’ll know we’re on the right track here.


#17

Hi Harry,

Sorry about not getting back to you earlier, but work/weekend got in the way…

Thanks for your efforts. I have just made the change from 10 to 100, so I’ll check the readings over the next couple of hours to see if the temp jumps. I only did it to one build, so we should only see one temp jump if we are on the right track.

Cheers.


#18

Hi Harry,
Software changed and uploaded, running for almost two hours, 8 readings, no jump ion temp observed.

code changed in device to,…

// instantiate our thermistor class
myThermistor <- thermistor(temp_sns, b_therm, t0_therm, 100, false);
//

Cheers.


#19

Hi Keith, thanks for running this test and reporting the result, which is causing a certain amount of head scratching here. We’ll do some more testing and try again to replicate it. I’m determined to get to the bottom of it!


#20

I built my own version of this project, following the Instructable (modified to use a resistor instead of a thermistor, to server.log() results in the device Squirrel instead of sending them to the agent, to log more frequently, and to log ADC results as well as ‘temperature’).

With this setup, I can’t replicate the problem on my imp001 / April board. Using a resistor instead of a thermistor should remove the noise from real temperature changes, exposing better any ADC calibration changes caused by firmware updates. But in this log I can’t see any evidence of this firmware effect.
