There are some methods to set the value of "HID Information Characteristic Value" and other Characteristic Value ??
I just found "hogpd_set_report_map_req_handler" that is a function to set "Report Map Characteristic Value"

I try to create a function that is similar to "hogpd_set_report_map_req_handler". The function run , but it did not work.

static int hogpd_set_hid_info_val_req_handler(ke_msg_id_t const msgid,
struct hogpd_set_report_map_req const *param,
ke_task_id_t const dest_id,
ke_task_id_t const src_id)
{
// Status
uint8_t status = PRF_ERR_INVALID_PARAM;

// Check Report map value length
if (param->report_map_len <= sizeof(struct hids_hid_info))
{
// Check HIDS instance - The Report Map Characteristic is mandatory and has been added.
if (param->hids_nb < hogpd_env.hids_nb)
{
// Set Report Map Char. Value
#ifndef USE_ONE_HIDS_INSTANCE
status = attmdb_att_set_value(hogpd_env.shdl[param->hids_nb] + hogpd_env.att_tbl[param->hids_nb][HOGPD_HID_INFO_CHAR] + 1,
param->report_map_len,
(uint8_t *)¶m->report_map[0]);
#else
status = attmdb_att_set_value(hogpd_env.shdl[0] + hogpd_env.att_tbl[0][HOGPD_HID_INFO_CHAR] + 1,
param->report_map_len,
(uint8_t *)¶m->report_map[0]);
#endif
}
else
{
// Report Map Char. is not in the DB - Request disallowed
status = PRF_ERR_REQ_DISALLOWED;
}
}

if (status != PRF_ERR_OK)
{
// The connection doesn't exist, request disallowed
prf_server_error_ind_send((prf_env_struct *)&hogpd_env, status,
HOGPD_ERROR_IND, HOGPD_SET_CHAR_VAL_REQ);
}

return (KE_MSG_CONSUMED);
}
