HID demo restart cound't control any more

[micele]

I programmed to nRF51 DK, the first time the device is connected to mobile phone.It works, but if i turn off the nRF51 DK and then turn it on.it is connected but it cound't control any more. This is my demo nRF51822_HID_KEYBOARD_MOUSE_C_20170926.rar.

#define DM_GATT_CCCD_COUNT 9

Ithink here have a question.

Also change the function on_hids_evt() in main.c so it looks like this:

static void on_hids_evt(ble_hids_t *p_hids, ble_hids_evt_t *p_evt)
{
    switch (p_evt->evt_type)
    {
        case BLE_HIDS_EVT_BOOT_MODE_ENTERED:
            m_in_boot_mode = true;
            break;

        case BLE_HIDS_EVT_REPORT_MODE_ENTERED:
            m_in_boot_mode = false;
            break;
        case BLE_HIDS_EVT_REP_CHAR_WRITE:
            on_hid_rep_char_write(p_evt);
            break;

        case BLE_HIDS_EVT_NOTIF_ENABLED:
        {
            dm_service_context_t service_context;
            service_context.service_type        = DM_PROTOCOL_CNTXT_GATT_SRVR_ID;
            service_context.context_data.len    = 0;
            service_context.context_data.p_data = NULL;
            if (m_in_boot_mode)
            {

                {
