Whitelisting and/or setScanFilter of BLE server not working
Posted: Fri Jan 15, 2021 12:24 pm
Hi there,
I'm having simple BLE server and trying to allow connections only from whitelisted devices, but without success.
All actions are done in setup like this:
When I execute code in Nano32, created BLE server is visible for scans, but it doesn't allow connection from whitelisted device (or any other device). Everything works, if I change to
But of course connections from all devices are accepted.
Could someone explain what I'm doing wrong?
Thanks in advance!

pCharacteristic->setValue("Hello World!");
pService->start();
// Try to whitelist
BLEAddress adrr = BLEAddress("a0:28:ed:8d:dc:f3");
BLEDevice::whiteListAdd(adrr);
