Hi hardy.chen and boont

Per the details in this thread: Disconnected happened right after connection

We are running into the same issue on 20737. Could I get some info on how you were able to resolve this issue,


Thanks

Can you provide some logs? Your issue could be unique in its own way...

I am programing on MAC, not using the IDE. So i dont have any standard logs. But I can describe my situation.

After many successful connections with the peripheral device, 20737(central) receives a disconnect with reason 0x08.

And every successive connection attempt after that also disconnects with reason 0x08. The only way to establish a good connection with the peripheral is to hard reset the 20737.

Below are the list of things that I tried to fix this problem:

Changed the connection parameters ----

   blecen_cen_cfg.high_conn_max_interval   = 40;       // frames

  blecen_cen_cfg.low_conn_max_interval    = 48;      // frames

  blecen_cen_cfg.low_supervision_timeout    = 700;      // N * 10ms

  blecen_cen_cfg.high_supervision_timeout   = 400;


Update connection parameter in connection up handler ----

lel2cap_sendConnParamUpdateReq();  Re: DiscReason 08


Fake a timeout so the indication queue is cleared and freed, in the connection down handler -----

leatt_timeoutCallback(0);  Re: Problem when client disconnection during Indication/confirmation phase.

Retry connection in connection down handler -----

blecli_ClientHandleReset();

blecen_connDown();


None of these have helped fix this problem.

Pardon me.. What do you mean when you said you are not using the IDE? Did you download our SDK and build your app in it?

Yes I am using the WICED Smart Software Development Kit 2.2.1. However I am not using the wiced smart IDE.

I compile and download from the command line.

Can you furnish some air trace? That may help us to understand some of the issues.
