Hi Everyone,
I am using nrf52840 in my project which is used as a central device. I have my app through which I can send data to the central device. The device is also able to receive the data and process it. Now when I want to send back the data to the app I am getting hard fault handler. I am trying to send only 5 bytes of data. I have attached my files over here for reference. Please help me out. I am using sdk 17.0.2.

* @brief Aquai Repeater Service Service implementation.
*
* @details The Aquai Service is a simple GATT-based service with TX and RX characteristics.
* Data received from the peer is passed to the application, and the data received
* from the application of this service is sent to the peer as Handle Value
* Notifications. This module demonstrates how to implement a custom GATT-based
* service and characteristics using the SoftDevice. The service
* is used by the application to send and receive ASCII text strings to and from the
* peer.
*
* @note The application must register this module as BLE event observer using the
* NRF_SDH_BLE_OBSERVER macro. Example:
* @code
* ble_aqrs_t instance;
* NRF_SDH_BLE_OBSERVER(anything, BLE_AQRS_BLE_OBSERVER_PRIO,
