Hi Alan

1. Do you mean why the pairing is done by button press? The pairing mechanism has been implemented for the purpose of making the examples user friendly. This is not a part of the Thread or CoAP specification.

2. I'm sorry but I am finding some of your questions hard to understand. I think the server has pairing enabled for 5 seconds. (See thread_coap_utils_provisioning_enable function in thread_coap_utils.c)

3. The best way to make sure only your devices connect to your network would be to hardcode some of the Dataset parameters, i.e. Extended PAN ID and/or MasterKey, that are found in dataset.h. You will have to add them to your sdk_config.h file and give them specific values, as they are, by default, random. It could be easier to use the nRF Thread topology monitor to keep track of your Thread network

4. Thread documentation is unfortunately rather scarce, and you will have to make due with what our Documentation Library has to offer on security documentation for Thread.

5. The pairing is added to make the examples easy to pair, and are in all our Thread examples, they are by no means required.

6. Yes, this should be possible, but we don't have an example project for you. I suggest you look into for example the MQTT which should be able to send a payload in a Thread network.

Best regards,

Simon
