BLE FOTA APP
It doesn't work with the default FOTA bootloader. It use NVIC_SystemReset() to enter a bootloader.

During initialization it adds the Human Interface Device Service and * a set of characteristics as per the Human Interface Device Service specification and * the user requirements to the BLE stack database. * * If enabled, notification of Input Report characteristics is performed when the * application calls the corresponding ble_hids_xx_input_report_send() function. * * If an event handler is supplied by the application, the Human Interface Device Service * will generate Human Interface Device Service events to the application. * * @note The application must propagate BLE stack events to the Human Interface Device Service * module by calling ble_hids_on_ble_evt() from the @ref ble_stack_handler callback. * * @note Attention! * To maintain compliance with Nordic Semiconductor ASA Bluetooth profile * qualification listings, this section of source code must not be modified. */ #ifndef BLE_HIDS_H__ #define BLE_HIDS_H__ #include <stdint.h> #include <stdbool.h> #include "ble.h" #include "ble_srv_common.h" // Report Type values #define BLE_HIDS_REP_TYPE_INPUT 1 #define BLE_HIDS_REP_TYPE_OUTPUT 2 #define BLE_HIDS_REP_TYPE_FEATURE 3 // Maximum number of the various Report Types #define BLE_HIDS_MAX_INPUT_REP 10 #define BLE_HIDS_MAX_OUTPUT_REP 10 #define BLE_HIDS_MAX_FEATURE_REP 10 // Information Flags #define HID_INFO_FLAG_REMOTE_WAKE_MSK 0x01 #define HID_INFO_FLAG_NORMALLY_CONNECTABLE_MSK 0x02 /**@brief HID Service characteristic id. */ typedef struct { uint16_t uuid; /**< UUID of characteristic. */ uint8_t rep_type; /**< Type of report (only used for BLE_UUID_REPORT_CHAR, see @ref BLE_HIDS_REPORT_TYPE). */ uint8_t rep_index; /**< Index of the characteristic (only used for BLE_UUID_REPORT_CHAR). */ } ble_hids_char_id_t; /**@brief HID Service event type. */ typedef enum { BLE_HIDS_EVT_HOST_SUSP, /**< Suspend command received. */ BLE_HIDS_EVT_HOST_EXIT_SUSP, /**< Exit suspend command received. */ BLE_HIDS_EVT_NOTIF_ENABLED, /**< Notification enabled event. */ BLE_HIDS_EVT_NOTIF_DISABLED, /**< Notification disabled event. */ BLE_HIDS_EVT_REP_CHAR_WRITE, /**< A new value has been written to an Report characteristic. */ BLE_HIDS_EVT_BOOT_MODE_ENTERED, /**< Boot mode entered. */ BLE_HIDS_EVT_REPORT_MODE_ENTERED, /**< Report mode entered. */ BLE_HIDS_EVT_REPORT_READ /**< Read with response */ } ble_hids_evt_type_t; /**@brief HID Service event. */ typedef struct { ble_hids_evt_type_t evt_type; /**< Type of event. */ union { struct { ble_hids_char_id_t char_id; /**< Id of characteristic for which notification has been started. */ } notification; struct { ble_hids_char_id_t char_id; /**< Id of characteristic having been written. */ uint16_t offset; /**< Offset for the write operation. */ uint16_t len; /**< Length of the incoming data. */ uint8_t* data; /**< Incoming data, variable length */ } char_write; struct { ble_hids_char_id_t char_id; /**< Id of characteristic being read. */ } char_auth_read; } params; ble_evt_t * p_ble_evt; /**< corresponding received ble event, NULL if not relevant */ } ble_hids_evt_t; // Forward declaration of the ble_hids_t type. typedef struct ble_hids_s ble_hids_t; /**@brief HID Service event handler type. */ typedef void (*ble_hids_evt_handler_t) (ble_hids_t * p_hids, ble_hids_evt_t * p_evt); /**@brief HID Information characteristic value. */ typedef struct { uint16_t bcd_hid; /**< 16-bit unsigned integer representing version number of base USB HID Specification implemented by HID Device */ uint8_t b_country_code; /**< Identifies which country the hardware is localized for.
