Yes, something like that is a rough estimate of a battery state.

Good luck with the project!

Cheers,

Bojan.

Thanks a lot bojan! I also found this chart https://devzone.nordicsemi.com/f/nordic-q-a/55692/thingy91-battery-fuel-gauge

It depends on the battery you are using. Li-Ion batteries have voltage in the range from 3.6 to 4.2V. You should read the battery datasheet to have a rough insight into how the battery voltage is translated into battery capacity.

% obtained in such a way is a rough estimate, I repeat.

Bojan.

Hi,

Thanks a lot for the reply! I will try the AT%XVBAT. How do you do the conversion to know the % ? I mean which are the maximum and minimum voltage so i can do the math ?

Hi RicardoPereira.

I used AT command only, as suggested by MJD093. Did not fight with the ADP536x module.

Regards,

Bojan.

Hi, were you able to find the problem ? i'm having the same issue. DT_NORDIC_NRF_I2C_I2C_2_LABEL is not declared. Any ideas ?

Hey MJD093!

This can do the job for us at this moment. Thank you very much for your suggestion!

Anyway, even though we are good at the moment, I would like to know how can we include ADP536x in the tree and communicate with it.

Cheers,

Bojan.

Hi,

If you just want the battery level in voltage, have you considered the AT command XVBAT? That will fire out the current battery level in mVs and doesn't require any communication with the PMIC.
