Hello! I'm trying ble_keyboard example, the advertising and connection is good. But I cannot receive any content after connected to my mac. Here is the log:

Appreciate if anyone can help

Could you try adding resolve_rpa() to security?

    device
      .security()
      .set_auth(AuthReq::all())
      .set_io_cap(SecurityIOCap::NoInputNoOutput);
      .resolve_rpa();

Yeah, that works! I opened a PR adding this to keyboard example

taks / esp32-nimble

ble_keyboard example doesn't work #119
