Hello Cypress support team.
Does CYW20819 support BLE Out Of Band paring? yes or no?
If yes, please provide the sample code to verify it.
Yes. It supports out of Band pairing.
There is no specific example code to test the OOB pairing only. We may have to add the OOB pairing mechanism in the existing code example (Eg. hello sensor/client) and test in it.
