https://devzone.nordicsemi.com/f/nordic-q-a/113066/gatt-service-discovery---hard-faultSupport, Due to the limitations described in the referenced previous ticket, I am unable to successfully discover a service and its characteristics because of a hard fault occurrence. This fault does not occur when compiling and executing under debugen-USTelligent Community 13Tue, 16 Jul 2024 11:13:02 GMThttps://devzone.nordicsemi.com/thread/494106?ContentTypeID=1Tue, 16 Jul 2024 11:13:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:56652fe0-8e0d-40ec-8b36-db4919a65100Vidar Berg<p>Hello,</p> <p>Is it the the app error handler or the&nbsp;HardFault handler that gets invoked in your application? Enabling the&nbsp;<a href="https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/lib_hardfault.html">HardFault handling library</a> by setting HARDFAULT_HANDLER_ENABLED to 1 in sdk_config.h and including the fault handler from /components/libraries/hardfault/nrf52/handler in your project may help us better understand the nature of the fault if it is the latter<span>.</span></p> <p>From the code snippets you posted, it appears that you have forgotten to allocate memory for your m_ble_device_srv pointer(s). Since you know the number of services you will discover beforehand, I recommend allocating the service struct statically.</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
