uint16_t GATTS_SetMinEncKeySize(uint8_t svcUuidLength, uint8_t *p_svcUuid, uint8_t minKeySize);Description
Set minimum encryption key length of a service.
Note
This function is used to set minimum key size requirement for accessing attributes in a GATT Service. Some of attributes required encryption permission to be accessed by remote client. Encryption with shorter key will be rejected when accessing those attributes.
