OpenThread COAP Client to a public server over Internet

Hello,

I am trying to make a Thread COAP Client on nRF52840 DK work with coap.me public server. I have created a Border Router with a Raspberry Pi and a nRF52 dongle and I am sure that it works as I can ping and run COAP CLI commands successfully with the OpenThread CLI sample. I can COAP GET and PUT to coap.me.

The coap.me IPv6 address was converted by me with the well known 64:ff9b::/96 prefix. The path was added to the border router as I can see with ot netdata show.

The problem is with the COAP Client sample provided. I modified the destination IPv6 address to be the same I use with the CLI sample and the URI path to "coap://coap.me:5683/hello". I have also tried just "hello". No luck so far.

As I said the CLI sample works fine: I get a response which is "world". Here the CLI commands I use after having joined the Thread network:

ot coap start

ot coap get 64:ff9b:0:0:0:0:8666:da12 hello

NOTE: in my COAP client program the Thread network is joined automatically as I have added the following options:

CONFIG_OPENTHREAD_JOINER=y
CONFIG_OPENTHREAD_JOINER_AUTOSTART=y
CONFIG_OPENTHREAD_JOINER_PSKD="J01NME"

Indeed I can ping the Border router IPV6 address from my board running the modified COAP Client and vice-versa so they see each other.

Can you please help to understand why my program directly derived from your COAP client sample does not work while CLI works fine?

Thank you.

Marco

Hi Arun, I can't share my code for contract reasons as I am working for a customer of mine. Anyway the source code shared above Charlie is still available and it is what I based my application on. However…

Hi Marco,

Sorry, I understand what you mean now. Could you share your modification to the CoAP client sample and log during running?

The reason is to demonstrate developers different CoAP API options they can use for the development, but Zephyr’s CoAP API is the encouraged option.

Best regards,

Charlie

I did some code clean up and launched the program again to capture the log for you.

The behaviour is the same. Looks like the UDP frame is sent and received back without going out. I have disabled 802.15.4 frames log but let me know if you want me to capture again with that enabled. For now only IPV6 log is enabled.

I also had to increase the coap thread stack size in coap_utils.c (nrf/subsys/net/lib/coap_util).

I had to rename the .conf file to .txt

FYI the IPV6 destination address is the well-known prefix 64:ff9b:: (as mentioned above) added to 0x86, 0x66, 0xda, 0x12 which is IPV4 134.102.218.18 (coap.me).

Hi Marco，

Sorry for the late reply. I can repeat your issue, need a bit more time to debug the issue plus traveling.

I will try to give you a reply next week. Is this OK for you?

Best regards,

Hi Charlie I just want to let you know that I have the same problem with the OT APIs directly. I can't even ping a remote server.

I have attached my new source code.

Cheers.
