/* Size of command/events buffers:
 *
 * To change the size of commands and events parameters used in the
 * auto-generated files, you need to update 2 defines:
 *
 *  - BLE_CMD_MAX_PARAM_LEN          
 *  - BLE_EVT_MAX_PARAM_LEN          
 *
 * These 2 defines are set below with default values and can be changed.
 *
 * To compute the value to support a characteristic of 512 bytes for a specific
 * command or an event, you need to look in "ble_types.h".
 *
 * Here are 2 examples, one with a command and one with an event:
 *
 * - aci_gatt_update_char_value_ext_cp0
 *   ----------------------------------
 *
 *   we have in the structure:
 *
 *      uint8_t Value[(BLE_CMD_MAX_PARAM_LEN- 12)/sizeof(uint8_t)];
 *
 *   so to support a 512 byte value, we need to have
 *
 *   BLE_CMD_MAX_PARAM_LEN at least equal to: 512 + 12 = 524
 *
 * - aci_gatt_read_handle_value_rp0
 *   ------------------------------
 *
 *   we have in the structure:
 *
 *     uint8_t Value[((BLE_EVT_MAX_PARAM_LEN - 3) - 5)/sizeof(uint8_t)];
 *
 *   so to support a 512 byte value, we need to have
 *
 *   BLE_EVT_MAX_PARAM_LEN at least equal to: 512 + 3 + 5 = 520
 *
 * If you need several events or commands with 512-size values, you need to
 * take the maximum values for BLE_EVT_MAX_PARAM_LEN and BLE_CMD_MAX_PARAM_LEN.
