Help powering device via battery

Products & Technology Grove
1

I have tried searching for this, but haven’t found any relevant answers yet.

I have a SeeedStudio ESP32-C6 connected to the Grove Shield for XIAO with battery management chip and an SHT31 to monitor temperature and humidity.

When I connect this to my USB cable, everything works fine, but ideally, I want to connect it via battery so that I can move it around, or place it in areas without outlets.
When I try to connect with the battery, I am not able to get it to work at all. I am new to this, so not 100% sure if the issue is the battery (3.7V Li-Ion 3000mAh with jst 2mm connector), my setup, or the code.

What I have tried to to use the little L-shape connector that came with the board and plug it into the +ve and -ve terminals/holes in the expansion board, and then connect the other pins to the jst connector of the battery, ensuring that the +ve from the board is the +ve on the battery, and same for the -ve connectors.

Anyone have any hints to help me out?

Thanks!

HI there,

And Welcome here…

SO, It’s a common mistake , and happens often.
If you have "while Serial " statement in your code , It won’t run “UNTIL” you connect the Serial device (usb-c) to the computer.

Comment out the While serial ,(waiting on port) and go again . It should work on battery just fine.
Have a look at the Grove Expansion demo code and video I have on here.

You can use the code tags above to paste you code for comments. “</>” :backhand_index_pointing_left: paste it in there. :+1:

Hi PJ,

Thanks for your reply. While my code with have the “while Serial” in it, it was calling the serial device using “serial.being(115200)” and commenting that out, and all other serial lines resolved the issue.

Thanks so much for your assistance. I am just getting into this, and I am sure that as I try to build more sensors, I will have more questions.

Thanks,

Andre
