Application Command issue in 'examples/freemaster_examples/fmstr_example_pdbdm

Dear All

Downloaded sdk.sdk_2.x_lpcxpresso54114 with only FreeMASTER examples. It works correctly in any aspect apart the Application Command section where I find strange behavior

More details has been posted in github here:

Hello, if I understand the issue correctly, you do not see a reason why command 0x10 returns code 16 in the example application.

The command 0x10 is registered for a callback function:

So the function "my_appcmd_handler" gets called automatically when FreeMASTER probes the command execution. The example code of this callback is quite trivial:

Which is the reason you get the return code 16 (=0x10) as answer.

I also confirm there is an issue in FreeMASTER with displaying a message for unknown responses as you reported for app.command with Id 0x02. The response 0xcd should be reported as "unknown response" but generates no message at all.

Thanks,
Michal
