"mbed-os-example-mesh-minimal"WiSUN application on Thunderboard Sense 2 borad cannot get connected!
I built "mbed-os-example-mesh-minimal"Thread and WiSUN applications for Thunderboard Sense 2 board . To compile WiSUN without error, I removed "s2lp.provide-default": true from mbed_app.json file.
When I press and release the reset button on Thunderboard Sense 2 board I have the following prompts on serial terminal:
For Thread application:
Start mesh-minimal application Build: Aug 23 2019 09:35:25 Mesh type: MBED_CONF_NSAPI_DEFAULT_MESH_TYPE Mbed OS version: 5.13.2 Device EUI64 address = ff:57:0b:00:de:8f:64:fe Connecting... Connected. IP = fd00:db8::ff:fe00:7c00
For WiSUN application:
Start mesh-minimal application Build: Aug 23 2019 15:01:33 Mesh type: MBED_CONF_NSAPI_DEFAULT_MESH_TYPE Mbed OS version: 5.13.2 Connecting...
So on WiSUN application, it does not show Connected. IP and Device EUI64 address.
Sincerely,
Mehdi

Hi Mehdi,
Thank you for your question!
As you can see from the code:
void thread_eui64_trace() { #define LOWPAN 1 #define THREAD 2 #if MBED_CONF_NSAPI_DEFAULT_MESH_TYPE == THREAD && (MBED_VERSION >= MBED_ENCODE_VERSION(5,10,0)) uint8_t eui64[8] = {0}; static_cast<ThreadInterface*>(mesh)->device_eui64_get(eui64); printf("Device EUI64 address = %02x:%02x:%02x:%02x:%02x:%02x:%02x:%02x\n", eui64[0], eui64[1], eui64[2], eui64[3], eui64[4], eui64[5], eui64[6], eui64[7]); #endif }
The "Device EUI64 address" will be shown only for THREAD mesh interface. However, you should be seeing the "connected" message. There are two possible locations where you r device is probably stuck: 1. int error = mesh->connect();
Perhaps the connecting part is stuck in a blocking loop
2. while (NULL == mesh->get_ip_address()) ThisThread::sleep_for(500);
I believe this is more likely the reason for your device being stuck.
Unfortunately, I don't have a Wisun environment to check this. Could you add a trace after the "connect" call (line 91) to check if the connection succeeded and the issue is ip address being NULL?

Mbed OS support
