I think you can use the size utility for GCC. data + bss should be the total RAM usage.

$ size file.out

   text       data        bss        dec        hex    filename
 0x1408       0x18      0x81c       7228       1c3c    file.out

Best regards,

Okay, is there anyway to understand how much ram i am using, on the gcc compiler? Or bss+data from .out file can show me how much ram i am using.

Thank you Simon.

We have examples for adding services and characteristics, please see this tutorial for example, but we do not have any specifically for the nRF52810. You'll have to keep in mind that the RAM is only 24kB on the nRF52810, so the total RAM usage of your application needs to be lower than this. I assume that changing NRF_SDH_BLE_GATTS_ATTR_TAB_SIZE was changed to value(s) greater than 24kB, which causes it to work on the PCA10040 DK, which has an nRF52832 with more RAM on it, and not the actual nRF52810 chip.

Best regards,

I already did all of these. I wanna know is it possible add 3 characteristics and 1 gatt service to my NRF52810 and are there any example for this.

Thank you Simon.

If you're using a 10040e project on an nRF52810 chip, please make sure that you've made the necessary steps to transfer an emulated project to nRF52810 hardware.
