NimBLE: Get properties from characteristic

[RootDev4]

Hi,

I need to know which properties are set to a characteristic.
My characteristic has the properties:

ble_characteristic = ble_service->createCharacteristic("d3ad", 
        NIMBLE_PROPERTY::READ | 
        NIMBLE_PROPERTY::READ_ENC |
        NIMBLE_PROPERTY::READ_AUTHEN |
        NIMBLE_PROPERTY::NOTIFY
);

uint16_t prop1 = ble_characteristic->getProperties(); // gives me the value 1554 which is the sum of all property values

I know that each property has its own value from NimBleLocalValueAttribute.h and blue_gatt.h respectively (for example NIMBLE_PROPERTY::NOTIFY is 0x0010, which is 16), but how to get each property from the value 1554?

Thanks for your help!

The properties are a bitmask so you need to test the bits, eg. prop1 & NIMBLE_PROPERTY::NOTIFY ? printf("notify set\n") : printf("notify not set\n");

Thank you @h2zero, it works!

prop1 & NIMBLE_PROPERTY::NOTIFY ? printf("notify set\n") : printf("notify not set\n");
prop1 & NIMBLE_PROPERTY::READ ? printf("read set\n") : printf("read not set\n");
prop1 & NIMBLE_PROPERTY::WRITE ? printf("write set\n") : printf("write not set\n");
