nRF52832-DK ble_app_uart ble_app_hrs 32K-byte problem

[sfujimoto]

I am trying to add the heart_rate_meas function to the ble_app_uart project. Is this plan possible? However, it does not go well. Why are you concerned with this method because the ble_app_hrs project is close to the KEIL-IDE 32 kbyte limit. Is there any good plan?

Hi,

Yes, it is possible to add the heart rate service to the ble_app_uart project.

But, if you originally wanted to use the ble_app_hrs project, you could disable the peer manager in order to reduce the code size. This will reduce the code size with about 12kB. Comment out line 1010 peer_manager_init(erase_bonds); and line 785 pm_on_ble_evt(p_ble_evt);.

Note: You cannot do pairing and bonding when not using the peer manager. The peer manager is not used in the ble_app_uart project.

Edit: Added ble_app_uart project with HRS.

PS: If you still want to use the ble_app_uart project, I could write a quick guide on how to add the heart rate service to the ble_app_uart project.

There was a way you guided us. Thank you very much. But, I am trying to add it to ble_app_uart, so please let me know if you like.

If it is okay, please let me know.

I have updated my answer with a ble_app_uart project where HRS is added. Extract it to

<SDK_InstallFolder>\examples\ble_peripheral\

Quickly summarized on how the HRS was added:

2. Go through the project files for HRS. Add the relevant files to the ble_app_uart project.

3. Include new header files

4. add all new defines and functions

5. update the sdk_config.h
