Losing cloud connection, Thread CoAP Cloud example (SDK 0.11.0)

[Reto]

Dear Thread-experts,

I have troubles with your Thread CoAP Cloud example. I am using:

• Thread SDK V0.11.0
• Border Router V0.11.0, ethernet (not Wi-Fi)
• cloud_coap_client example, adapted that I send more data (buffer size =256bytes)
• Eclipse
• Preview DVK, V0.9.0

I observe that after a while (sometimes day, sometimes minutes), no data are sent to the cloud. I debugged and my FW is running find and I don't get any errors (function otCoapSendRequest() is executed without error). However, the data is not visible in the cloud. The only way to recover it is: erasing the FW on the Border Router Network-Co-Processor-Thread-Module (Preview DVK). After erasing and reprogramming the DVK with the NCP, I can send data again for a certain time, until it brakes down again.

What I have observed is: when I send only 64bytes (insted of 256bytes): it tends to run more stable (some samples are missing, but the system is recovering itself).

I send the 256bytes every 6 minutes.

How can I debug that issue in more detail?

Thank you, Reto

I ran "make" to rebuild the libmbedcrypto-cc310.a. I checked the OPENTHREAD_CONFIG_LOG_LEVEL in the file openthread-core-default-config.h: it was already set to OT_LOG_LEVEL_CRIT. Then I copied the lates OpenThread commit to nRF_Thread_SDK0.11.0\external\openthread\project and ran build_gcc_libs.bat.

I changed the make file of my project accordingly: Libraries common to all targets

LIB_FILES += \
$(SDK_ROOT)/external/openthread/project/lib/openthread_cli/ftd/armgcc/libopenthread-cli-ftd.a \
$(SDK_ROOT)/external/openthread/project/lib/openthread/ftd/armgcc/libopenthread-ftd.a \
