Assigning a new NimBLEAddress at a later stage das not "equal"

[NorbertRoller]

Hi,
I tried everything I could think of, but I do not get it working.
I compare devices by MAC to connect and this works flawless.

class scanCallbacks : public NimBLEScanCallbacks // BLEAdvertisedDeviceCallbacks
{
    void onResult(const NimBLEAdvertisedDevice* advertisedDevice) override 
      {
      Serial.printf("NimBLE_scan: Discovered Device: %s Type: %d \n", advertisedDevice->toString().c_str(),advertisedDevice->getAddressType());

      // Checke for LiFePo4 MAC discovered
      if (advertisedDevice->getAddress().equals(MAC_LiPo4))

changing the MAC is where I struggle to get the .equals working
let me show you what I tried

This works:
NimBLEAddress MAC_LiPo4("a4:c1:37:01:22:5f", 0);
and in Setup
NimBLEAddress MAC_LiPo4("38:3b:26:b5:15:a2", 0);

Since I have to change it , I added this at the top (before setup) and this works.
char MAC_lithium[18] = {0x61,0x34,0x3A,0x63,0x31,0x3A,0x33,0x37,0x3A,0x30,0x31,0x3A,0x32,0x32,0x3A,0x35,0x66,0x00};
NimBLEAddress MAC_LiPo4(MAC_lithium, 0);

If I change the MAC_lithium[] in Setup and run
NimBLEAddress MAC_LiPo4(MAC_lithium, 0);
the .equals will always be false.

The snipped looks like this:

char MAC_lithium[18] = {0x61,0x34,0x3A,0x63,0x31,0x3A,0x33,0x37,0x3A,0x30,0x31,0x3A,0x32,0x32,0x3A,0x35,0x66,0x00};
char fake_MAC_lithium[18] = {0x6**4**,0x34,0x3A,0x63,0x31,0x3A,0x33,0x37,0x3A,0x30,0x31,0x3A,0x32,0x32,0x3A,0x35,0x66,0x00};
NimBLEAddress MAC_LiPo4(fake_MAC_lithium, 0); // 0=Public, 1= Random --- BLE_ADDR_PUBLIC (0) BLE_ADDR_RANDOM (1)

void setup(){
NimBLEAddress MAC_LiPo4(MAC_lithium, 0); // 0=Public, 1= Random --- BLE_ADDR_PUBLIC (0) BLE_ADDR_RANDOM (1)

Any help is appreciated

This compare works as well:
if(strcmp(advertisedDevice->getAddress().toString().c_str(), MAC_lithium) == 0)

Just the .equal will not

You cannot set a public address, when you call setOwnAddress it will assign the address as random, so the address type is different and therefore the comparison fails. To fix it, change the types to 1 in your code.

[NorbertRoller]

The device sends a private AddressType. Therefore I can not change the address type in the MAC I am searching for. So that is not a solution, or am I mistaken?

For reference I am using the following compare:

if(strcasecmp(advertisedDevice->getAddress().toString().c_str(), MAC_lithium) == 0)

Please see #777

The answer is in the comment from you code:

NimBLEAddress MAC_LiPo4(MAC_lithium, 0); // 0=Public, 1= Random --- BLE_ADDR_PUBLIC (0) BLE_ADDR_RANDOM (1)

That should be: NimBLEAddress MAC_LiPo4(MAC_lithium, 1);
