Hi Joakim
I got the new Thingy from Nordic Tech Tour 2018 today.
Gas sensor function is normally, old Thingy should have some problems
Thanks for your help

Hi!

Maybe you could send me a PM with information about where you got your Thingy:52?

Cheers.

Hi Joakim
I tried using raspberry pi 3 test situation is the same
The program I tested was linked from the sample code downloaded from github as follows github.com/.../Nordic-Thingy52-Nodejs

Hi again!

So I tested this with an Iphone 6 and it still works, and I get valid data for the air quality when testing it with Iphone 6 and your setup.
However, I only got the chance to test this using the latest iOS version.

Maybe you have another Thingy and/or a phone that you can use to test this?

Cheers.

Thank you! I will test this using your setup, and see if I am able to reproduce the issue.

I'll get back to you as soon as possible.

Cheers.

Ok, thanks for trying!

I talked to our team developing the Thingy, and they had never seen this either.

The softdevice is included in the precompiled hex file, so there is no need to do anything about the softdevice.
You don't need to flash the softdevice before the FW hex file either.

Just to eliminate all possible reasons for this issue, could you tell me how you are connecting to the thingy?
Are you using a phone? if so, which phone and OS are you using? (also OS version if possible)
Also, what version of the Thingy app are you running?

Cheers.

Hi Joakim
I tried to use the 52DK to update the Application
thingy_v1.1.0.HW_1.0.hex
thingy_v2.0.0.HW_1.0.hex
thingy_v2.1.0.HW_1.0.hex
The result is the same, the TVOC value is 0, if I need to update my version of SoftDevice
Thanks in advance

Hi!

That sounds strange!
I've never seen that before.
I tested this with my Thingy. After I updated to FW 2.1.0 and after running for 10-15 minutes it starts outputting valid data for the air quality.

Do you have a nRF52-DK or a programmer available?
If so, you could try to erase and reprogram your Nordic Thingy:52 with FW v2.1.0 using nRFgo Studio?

Please let me know if you are not able to reprogram your Thingy or that it doesn't solve the issue.

Best regards,
Joakim.

Hi Joakim

Yes , I had read the values before update firmware.

Before update firmware , blowing towards thingy 52 TVOC and eCO2 values will change

But now that I have operated thingy 52 for more than 4 hours , the values of TVOC is still 0 and the values of eCO2 doesn't

exceed 400ppm.

Is there a way to determine if the CCS811 sensor is faulty or other problem?

Thanks in advance.

Hi!

Did you get readings from it before the firmware update?

As far as I know the burn-in is only needed once. Not after every FW update.
However, the sensor datasheet recommends run-in of 20 minutes. So the sensor should be up and running for aprox. 20 minutes to output valid data.
