Thread Border Router networking fail

[Rick]

Hello Nordic Taam:

I follow the WEB steps below

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.1.0%2Fthread_ot_performance_measurement.html

Software Development Kit > nRF5 SDK for Thread and Zigbee v4.1.0 > Thread > Thread tools > Thread Border Router

nRF52840 DK Version：nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8\examples\thread\ncp\ftd\uart\hex

Raspberry Pi 3 Version：RaspPi_OT_Border_Router_Demo_v4.1.0-1.alpha

Use nRF52840 DK UART connect Raspberry Pi 3 to get the following information

wpan0 => [
"NCP:State" => "associating"
"Daemon:Enabled" => true
"NCP:Version" => "OPENTHREAD/20191113-00534-gc6a258e3; NRF52840; Apr 5 2020 21:51:18"
"Daemon:Version" => "0.08.00d (; Apr 21 2020 19:11:43)"
"Config:NCP:DriverName" => "spinel"
"NCP:HardwareAddress" => [F4CE363EC3C45B0E]
]

pi@raspberrypi:~ $ sudo wpanctl status
wpan0 => [
"NCP:State" => "uninitialized"
"Daemon:Enabled" => true
"NCP:Version" => ""
"Daemon:Version" => "0.08.00d (; Apr 21 2020 19:11:43)"
"Config:NCP:DriverName" => "spinel"
"NCP:HardwareAddress" => [F4CE363EC3C45B0E]
]

If I have the wrong steps or have not completed, please give me some pointers, thank you.

Also, can you teach me how to set up the Thread Border Router successfully on Raspberry Pi 3?

Best Regards

Rick.

Hi,

The instructions on Thread Border Router is the latest and should be correct. It also looks like you are using the correct versions of the firmware and border router image. 

I have tested this multiple times before, and have not had any issues with getting the network up and running.

Are you using a revision 1 DK or later? Did you have the DK connected to the RPi before you booted it? Did you run 'erase all' command on the DK before flashing the NCP FW? You did not run any other commands on the border router prior to the "sudo wpanctl status" command?

If nothing works, I would suggest that you start over and flash the DK and border router image again to the devices to see if that solves any issues.

Best regards,
Jørgen

Hi Jørgen:

How are you today!

Is there any update?

Pls kindly help advise how to solve it?

Best Regards,

Rick.

Hi Jørgen：

I want to get the IP address for Openthread device from the border router or mobile phone, how can get it?
because I have a case, need to use a mobile phone control Openthread device.
or you have good kindly advised?

I use version is:
nRF52840 DK Version：nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8\examples\thread\ncp\ftd\uart\hex

Raspberry Pi 3 Version：RaspPi_OT_Border_Router_Demo_v4.1.0-1.alpha

1. Pls kindly advise how to get IP Address of all Thread devices?

2. Pls kindly advise how to get locate the IP Address of other Mesh Local devices from Border Router or End Device?

3. Pls kindly advise how can get IP address of other Router and End device from Border Router?

4.Pls kindly advise how to get the IP Address, assigned by the Border Router, to the Devices?

5. Pls kindly advise how can see any Thread log from Border Router? (ex. IP assigned, join flow, -MLE----- information et. )

Best Regards,

Rick.

Hi,

1.-4. See this page for detail pg IPv6 addressing used by OpenThread. You can get Mesh- and Link-Local address of nodes by doing a multicast ping to the ff02::1/ff03::1 addresses from the Border Router:

Link-Local:

pi@raspberrypi:~ $ ping -6 -I wpan0 ff02::1
PING ff02::1(ff02::1) from fe80::900e:ea92:8be6:51f8%wpan0 wpan0: 56 data bytes
64 bytes from fe80::900e:ea92:8be6:51f8%wpan0: icmp_seq=1 ttl=64 time=0.193 ms
64 bytes from fe80::1028:aa0a:fd4c:649%wpan0: icmp_seq=1 ttl=64 time=36.5 ms (DUP!)
64 bytes from fe80::a813:d16e:3821:861e%wpan0: icmp_seq=1 ttl=64 time=48.4 ms (DUP!)
^C
--- ff02::1 ping statistics ---
1 packets transmitted, 1 received, +2 duplicates, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.193/28.411/48.481/20.538 ms

Mesh-Local:

pi@raspberrypi:~ $ ping -6 -I wpan0 ff03::1
PING ff03::1(ff03::1) from fd11:22::ec33:5809:17a8:aa3a wpan0: 56 data bytes
64 bytes from fd11:22::ec33:5809:17a8:aa3a: icmp_seq=1 ttl=64 time=0.199 ms
64 bytes from fd11:22::52db:33fd:683f:65dc: icmp_seq=1 ttl=64 time=37.8 ms (DUP!)
64 bytes from fd11:22::b3eb:df1f:8f1c:aeaf: icmp_seq=1 ttl=64 time=49.7 ms (DUP!)
^C
--- ff03::1 ping statistics ---
1 packets transmitted, 1 received, +2 duplicates, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 0.199/29.271/49.773/21.126 ms

You can also get the RLOC16 address of all routers in the network from the RouterTable property:

pi@raspberrypi:~ $ sudo wpanctl getprop "Thread:RouterTable"
Thread:RouterTable = [
        "920EEA928BE651F8, RLOC16:0000, RouterId:0, NextHop:63, PathCost:0, LQIn:0, LQOut:0, Age:0, LinkEst:no"
        "1228AA0AFD4C0649, RLOC16:4400, RouterId:17, NextHop:41, PathCost:1, LQIn:3, LQOut:3, Age:8, LinkEst:yes"
        "AA13D16E3821861E, RLOC16:a400, RouterId:41, NextHop:17, PathCost:1, LQIn:3, LQOut:3, Age:31, LinkEst:yes"
]

The nodes can be addressed using the MeshLocal prefix + 0000:00ff:fe00:RLOC16, for instance fdde:ad00:beef::ff:fe00:4400.

5. You can view logs in Syslog, see the instructions on this page. The grep string may not work with our SDK example, but removing it should give you all Syslog output.

Jørgen

Hi Jørgen

How are you today!

Thanks for your explanation.

But I have a case that needs to use the mobile phone or PC control the Thread Device. Pls kindly advise how can get the IP address of Thread Device from a mobile phone or PC?

Or you have any advice can be using a mobile phone or PC control Thread Device?

Best Regards,
Rick.

Hi Jørgen:

Are you have any advice?

Hi Rick,

I can't think of any simple way to do that. Does the phone/PC have IPv6 connectivity? Is the border router and the phone/PC in the same local network?

The nodes would somehow have to communicate with a central server/point, where the phone/PC could get their IP from a database. If the nodes and the phone/PC both have global IPv6 connectivity, it is possible to communicate directly between the nodes once the phone/PC get hold of the IPv6 addresses.

If you can provide more details about your use-case, we may be able to help you with finding the best approach and/or alternative solutions.

Best regards,
Jørgen

Hi Jørgen,

My case The border router and the phone/PC in the same local network, and is supported IPv6.

The premise Phone/PC does not know the Thread Network Device IP now.

So I need to search the Thread Device IP address from Phone/PC.

Best regards,
Rick

This is my case framework.

[Jørgen Holmefjord]

Hi,

I consulted with some colleagues and we can't think of any other solution to this than the one I already suggested in my previous post.

Neither the phone, nor the AP router is aware of the Thread network's presence. The Border Router is aware of the network and can do a multicast ping as I described before, in order to get IPv6 addresses of the Thread nodes. This can be stored in a known location where the phone can query the list of know devices. The nodes in the Thread network can also advertise themselves to a network/cloud server, where the phone can get the list of attached devices. This is not solutions that we provide today, but is something you need to implement as part of your system/solution.

Best regards,
Jørgen

Hi Jørgen

How are you today!

Thanks for your explanation.

the video nRF52840 running concurrent Thread and Bluetooth 5 (4:47),

it can control the BLE device from the thread network.
how to do it?
Do you have the example code?

Best Regards,
Rick.

[Jørgen Holmefjord]

Hi Rick,

This can be achieved using the BLE/Thread multiprotocol solution. Please have a look at the Dynamic multiprotocol examples in the SDK to find your best starting point.

Best regards,
Jørgen

Hi Jørgen

How are you today!

Thanks for your explanation.

the video Thread smart home demo example.

How do I simulate it??

Do you have the example code?

Best Regards,
Rick.
