Nordic Thingy 91 Low power version of Asset tracker v2 now does not send Barometric pressure nor button press data

[iarakis]

Hi,

I followed the procedure described here with Nordic Thingy 91 https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nowi-powered-energy-autonomous-nordic-thingy-91-platform

and now it works with low power consumption and sends data to NrfCloud, that is fine.

However, after adding the prj.conf file, now it does not send emvironmental pressure and button press values. How can still receilve those values into NrfCloud, along with temperature and moisture that I already receive?

Regards

Hi

If you check out the prj.conf file, you can see that a lot of configs has been disabled, like the CONFIG_LED_CONTROL, the serial interface, and a lot of log event configs has been set to "n". You can't expect super low current consumption and being able to get continuous logging information I'm afraid. You'll need to enable the configs you need again if you still want environmental pressure and button press values, etc.

Best regards,

Simon

I managed to configure so that I receive also button presses. But I don´t receive atmosferic pressure. What should I enable to receive pressure data?

[iarakis]

Ok, thanks. What about "connection timeout"?

[iarakis]

Hi, this seams to be the cause of the disconnecting.

"Disconnect Reason: MQTT_KEEP_ALIVE_TIMEOUT. The connection status will be updated no later than every 1800 seconds. Last updated 45 minutes ago."

How can I solve it?

[Markus Tacker (he/him)]

The device disconnected and did not reconnect, as mentioned above, we need more information:

Markus Tacker (he/him) said:

It's hard to say without more information about your configuration. The cause for disconnects is often because of the SIM card in use, so we need to know which kind you are using, and from which manufacturer. Please also attach a full log from the device and ideally a modem trace.

I am using IBASIS SIM car that comes with the Thingy91. How can I get the log we need or modem trace?

[Markus Tacker (he/him)]

You can get the application debug log from UART, either via USB or via BLE UART Service:

This device will advertise as "Thingy:91 UART".
Connect using a BLE Central device, for example a phone running the nRF Connect app:
www.nordicsemi.com/.../

NOTE: The BLE interface is unencrypted and intended to be used during debugging.
By default the BLE interface is disabled.
Enable it by setting the appropriate option in Config.txt.

How to acquire a modem trace is documented here.

Sorry,

With current code the Thingy is not advertising over BLE. Also I opened a serial terminal with Putty (it shows up two serial connections for the Thingy91) but nothing is printed out.

Do you need the serial log with this code or should I flash the original Asset Tracker V2 code?

Did you enable the UART service in the Thingy:91 config? The config is editable when you plug it in, the Thingy:91 will show up as a mountable drive.

Also make sure that UART is not disabled (e.g. the asset_tracker_v2's low-power overlay disables it).

How can I enable it back? What should I modify in the low power overlay?

This is the serial output over BLE:
