Hi,

After terminating a connection and restarting advertisements my 20737TAG will frequently enter into a failure mode where advertisements cannot be stopped. When the device is in that mode, the following commands will fail to stop advertisements:

blecm_setAdvEnable(0)

nor

bleprofile_Discoverable(NO_DISCOVERABLE, NULL)

I am sending these commands via my interactive debug console through the UART.

When that happens, I am also unable to change the advertisement data.

Other than this the device is functional, so I don't think this is a crash, at least not a full system.  Maybe the task that handles beacons dies? Has anyone experienced this?  Any recommendations on how to resolve it?

I am using the following commands to terminate connections:

blecm_disconnect(BT_ERROR_CODE_CONNECTION_TERMINATED_BY_LOCAL_HOST);

blecen_Conn(NO_CONN, NULL, 0);

I've tried several combinations of the above (just one of them, or both in swapped order) and I still observe the same problem.

Cheers,

Do you have a trace log of this you can post?

Hi arvinds,

Do you have a trace log of this you can post?

Yes, sure.

Below are the logs for the two devices I use to reproduce this problem.  In the initial state both devices advertise, then one connects to the other a couple of times, then they should go back to the initial state.

But what happens is that one of the devices enters this "unstoppable advertising" mode and will not be capable of initiating new connections.

Let me know this gives you any ideas on what might be wrong.

Cheers,

Hello Jcardona,

Can you try the new SDK 2.1.0?  It was just released on Friday; WICED Smart Documents &amp; Downloads

Let me know if this fixes your problem.

Thanks for letting me know, JT.  I'm on vacation and won't be able to try it until the end of the month.
