/* 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.
