[OoB_5.4.1] [NUCLEO_F429ZI + AT233 Thread + Thread BR]: Fails to connect/register object.

[ashok-rao]

Steps to reproduce:

1. Clone repo, switch branch, update example, update FW of BR with ThreadDynamic.bin. Make sure BR is up & running.
2. mbed compile -t ARM -m NUCLEO_F429ZI --app-config configs\mesh_thread.json -c
3. Flash binary to target.

Result: Fails to connect & register object. Full log (with trace enabled in mesh_thread.json) attached below. Thread_log.txt

BR is up & running as below:

@SeppoTakalo .. can you please have a look at this? Thanks!

[SeppoTakalo]

I think you stopped too quickly. In Thread network, the devices joins mesh before it has public IP address. First connection attempt most probably fails. Second one should already have public IP.

Let it try for at least those 3 times: M2MInterfaceImpl::socket_error - reconnecting in 15(s), count 1/3

I'll forward this issue to Thread team. In mbed OS interface API, we can only get one .connect() callback and Thread returns earlier that 6LoWPAN-ND.

Thanks @SeppoTakalo .. I tried it, but still the results are same. Here is a detailed explanation and full logs attached at appropriate places. Also, I started with a fresh mbed import & I'm using the oob-test-mbed-os-5.4.1 branch.

Here are the SHA's I'm using:

And here are the output logs. I have left the target to try to connect for >20 mins and if I read the logs right, I think it went through the 3/3 connect cycles three times (9 tries in total).

We are using a RPi as an IPv6 tunnel. From below log, we have a working IPv6 connection. So, green.. tunnel_ready.txt

The mbed GW is up and running with a valid IPv6 address as below. So, green.. mbed_GW.txt

The output from the target: RED. NUCLEO_F429ZI_AT233.txt

(Extra) If github comments becomes too lengthy, here is the log from cmd prmpt: cmd_prmpt.txt

Can you also try with another compiler, GCC? We have another issue where some connectivity issues are reported from ARM compiler (ONLY, GCC and IAR working OK).

[SeppoTakalo]

Also, does it work in 6LoWPAN-ND mode?

[artokin]

From mbed-os-5.4 onwards the Thread gateway binary file gatewayThreadDynamic.bin is configured to use RF channel 22 and panid 0x0700. There is no need to modify Thread configuration settings. Your steps sounds right in "steps to reproduce" chapter, the application should work in Thread mode when building application with configuration from ./configs/mesh_thread.json.

[artokin]

Tested mbed-os-example-client (NUCLEO_F429ZI + AT233, GCC_ARM) in our CI. The device was registered successfully in 3 minutes.

[ashok-rao]

Hello @JanneKiiskila , the result is same as before with GCC. With IAR, I get a memory allocation error at link time.

@artokin .. I flashed the GW again with ThreadDynamic.bin , reverted mbed_app.json to defaults and used --app-config with mesh_thread.json while building.

Happy to report that it works now with this. . This was the exact same setup I was using yesterday too, but it was failing & that is the reason I reported it. I suggest to remove or make optional the channel settings chapter in the docs to avoid confusions for users overriding these in mbed_app.json AND using the config json too. Thanks.

[artokin]

Good, we will update the misleading documentation.

[kseverinkangas-zg]

Document updated, closing the issue.
