Sorry, this nPM1300_one_button sample is only available in the main branch and will be added in future versions of the major/minor NCS releases. You can find the one_button sample source code in the NCS GitHub here: https://github.com/nrfconnect/sdk-nrf/tree/main/samples/pmic/native/npm1300_one_button

The setup seems fine, what connection issue exactly are you seeing when closing and opening the nPM PowerUp app?

Best regards,

Simon

Thanks for your reply! I don't seem to have that sample...? I searched in the directory to find it elsewhere, but it's not there?

"This sample can be found under samples/pmic/native/npm1300_one_button in the nRF Connect SDK folder structure."

I followed the suggested connections for npm1300->nrf5340dk, but on the nrf52832dk those pins are P0.19 - P0.24 instead of P0.10-P0.15

***VDD connected to VDDIO(npm1300ek) - I am getting connection problems when I close then open the PowerUp app. The problem seems like it might be tied to the VDDIO-VDD connection? Is this supposed to be connected?

From what I can see, the fuel gauge sample doesn't in fact use the SHPHLD. You can check out the nPM1300 One Button sample to see how the SHPHLD/RESET button is set up there to control the device state. Can you also share some details on how you're powering the nPM1300 on your end here, and how exactly the nPM1300 and nRF52832 DK is connected?

Best regards,

Simon
