{  
“req”: “card.aux”,  
“mode”: “track”,  
“sync”: true,  
“file”: “track.qo”  
}

Why does this not work to send temperature to Notehub?

Hi @jim and welcome to the Blues Wireless community!

Can you please verify that you have your BME280 wired up per the [instructions given here](https://dev.blues.io/notecard/notecard-walkthrough/advanced-notecard-configuration/#using-aux-track-mode)? Feel free to send a picture of your wiring if you have any doubts.

Thanks,  
Rob

I found the solution. Need to have motion.mode started for any of the tracking functions to work. Working great now. Thanks for the response.

I have the similar problem. I am using BME280 I2C sensor connected to AUX1, AUX4 pins as described in the documentation.

I have enabled the track mode using `card.location.track`. and “req”: “card.aux”, “mode”:“track”.  
then I am doing the sync. On the notehub side, I do not see a file \_track.qo or similar.
