To: linux-bluetooth@vger.kernel.org Content-Type: text/plain; charset=UTF-8 Sender: linux-bluetooth-owner@vger.kernel.org List-ID: I fail to understand what is happening here and I would appreciate your help. I'm able to see my nearby device (NRF51822DK) with the "scan on" command. However when calling "connect F1:6F:DE:EC:F1:D6" from bluetoothctl, I get a "connect failed" error... And from times to times, it magically works... meaning it gets a connect failed but eventually create a connection with a single "connect" command by the way. Here's a btmon trace below.
