How to implement 512 bytes characteristic in peripheral

[Paul]

Do we have any example for implementing a characteristic with more than 20 bytes? Thanks.

Example? Just set the length of the characteristic to what you want when you add it.

ble_gatts_attr_t.max_len
ble_gatts_attr_t.init_len

and note the defines

#define BLE_GATTS_FIX_ATTR_LEN_MAX (510)  /**< Maximum length for fixed length Attribute Values. */
#define BLE_GATTS_VAR_ATTR_LEN_MAX (512)  /**< Maximum length for variable length Attribute Values. */

I am testing the code right now. How do I define the attribute value to be fixed or variable? Thanks.
