Jam Detection Thread

[Verena]

Hey,

I am trying to use the Jam Detection Feature of Openthread on my nrf52840 DK. The device is running as coap server with the example code 

"simple coap server". I want to use the jamDetection in this code. I tried  to put the code you see down in the main file but it doesn't compile. I enabled the jamDetection in the config file and in the openthread file. 
How am I starting the Jamdetection? How can I put a Callback object in the otStartJamDetection function?

my function otJamDetectionIsEnabled(thread_ot_instance_get()) is alwys returning 0. Is this because there is no jamming at the moment or is it not really enanbled in the setting?

Or is there an example?

Best regards

#include <openthread/thread.h>
#include <openthread/jam_detection.h>
#include <openthread/cli.h>     
     
     otCliOutputFormat("is enabled %d",otJamDetectionIsEnabled(thread_ot_instance_get()));

     otError otError = otJamDetectionSetRssiThreshold(thread_ot_instance_get(), aRssiThreshold);
     APP_ERROR_CHECK(otError);

     otCliOutputFormat("rssi treshold %d", otJamDetectionGetRssiThreshold(thread_ot_instance_get()));
     otCliOutputFormat("history bitmap %d", otJamDetectionGetHistoryBitmap(thread_ot_instance_get()));

     otStartJamDetection(thread_ot_instance_get(), otJamDetectionCallback aCallback,p_context);
     otCliOutputFormat("get state %d",otJamDetectionGetState(thread_ot_instance_get()));

I enabled the Jam detection in openthread/src/core/config/openthread-core-config-check.h and also in the sdk_config.h .
But if I am calling the method otJamDetectionIsEnabled(thread_ot_instance_get())) i am always getting 0 back. The thread_ot_instance_get is a method which is getting the actuall instance. The instance is required as an argument  for  the function     *** bool otJamDetectionIsEnabled(  otInstance *aInstance ) ***.

In the instruction it is written to enable the jam detection in the openthread/src/core/config/openthread-core-default-config.h , but there is no such file in my openthread repository.

Where should I enable this to solve this problem?

My second problem is that I don't know how to call the starting function.

otError otJamDetectionStart(
  otInstance *aInstance,
  otJamDetectionCallback aCallback,
  void *aContext
)

This is out of the instruction, but I don't know how to give aCallback in this function. ainstance and aContext are already defined in some example code snippets, so I know these. Should I define my own function ? Or what should I place there.

I would be glad about some help.
