OTBR error: "Failed to process Discovery Request: Security"
Hi, I have an OTBR and a Thread device. I'm doing Thread commissioning with an Android phone (used as commissioner) and then I exchange some datagrams between the Thread device (freshly commissioned) and the Android phone.
I have noticed that the commissioning sometimes fails. I think that it is due to the following error, seen on the OTBR. Would you know in which cases the error "Failed to process Discovery Request: Security" happens?
Thank you Regards

@OlivierGre , this error typically indicates that the Network Data does not include a Commissioning Dataset TLV where the Steering Data value is non-zero.

@jwhui Jonathan: A side question. Once a Thread device commissioned, what is the way to disconnect it from Thread network? I'm interested because I want to re-execute the commissioning (for demo purprose). Thanks

Thread does not provide a way to remotely remove a device from the Thread network. You can add some application logic to trigger the equivalent of the factoryreset CLI command.
Hello,
I am using esp32h2beta2(ot_cli code) as a joiner and I have made commissioner (esp32s3(ot_br code)+esp32h2beta2(ot_rcp code))OTBR. esp-idf = v5.0.6 with command lines
I am getting this warning continuously when i try to connect joiner to the commissioner:

@jwhui have you solved the issue of security? If you have, would you please share the solution with me. It would be really helpful.
