    ConnTimer stopped

    hlee

      Sometimes, when the master and the slave try to connect, it fails and the message I saw is "ConnTimer stopped"

       

      14:13:49   ConnTimer stopped: 2

      14:13:49   BLE_low_conn:timer(0)

       

      What is this timer about and how to configure it?

          I don't think "ConnTimer" is something that you can configure. You may probably want to focus on why your devices failed to connect instead.

            What is the value of ConnTimer then?

             

            I sometimes got the error continuously and sometimes I did not get the error under the same setup.  See below I got 6 timeout within 4 seconds.  This is connection for one slave.  Any idea why this could happen sometimes?  How to troubleshooting this?  Thank you.

              1. Try increasing both high_scan_duration and low_scan_duration and let me know if that works. May be creating a loop of killing the connection while it's trying to start if the duration is too low.

               

              2. You say this is for a single slave, yet your traces show multiple connection timers running. I don't believe this should be happening.

               

              Reference hello_client.c in the connection down function. Ensure that you are properly dealing with dead connections. Specifically:

                The scan interval is set to maximum about 10 sec and the scan duration is about 3600 sec, but it's still the same.

                 

                Also, I used "blecm_startScan".

                 

                The slave sends out beacons every 500 ms.

                 

                Here is a log shows when the master node receive the beacons

                  Hi hlee

                   

                  Have you tried the below items? , because you mention the scan interval/

                   

                  blecen_cen_cfg.high_scan_duration       = 30;

                  blecen_cen_cfg.low_scan_duration        = 300;      // seconds

                    My understand is that "blecm_startScan" does not use "duration" since it will keep running.

                     

                    Nevertheless, my duration is set to very long seconds so they should have no impact.  (Consider my problem is within few seconds)

                     

                    blecen_cen_cfg.high_scan_duration       = 3600;

                    blecen_cen_cfg.low_scan_duration        = 3600;      // seconds

                     

                     

                    Also, I used sniffer and found that the master does NOT send out connection requests when blecen_Conn(LOW_CONN, evt->wd_addr, evt->addressType) was called.  It should be the reason we saw the error:

                     

                    18:53:52   ConnTimer stopped: 2

                    18:53:52   BLE_low_conn:timer(0)

                     

                    Is it possible to trace why the master does not send out connection request?

                      Can you post a snip of code that will allow us to emulate? (or email to community-manager@cypress.com)

                       

                      You only show failures with LOW_CONN parameters. Does the same thing happen with your HIGH_CONN parameters?

                        There are several conditions be checked under the blecen_Conn, the connection will be processed until  all the check be passed.

                         

                        Could you give me the parameters used on BLE connection?

                            1. Please add this library to WICED-Smart-SDK\Wiced-Smart\tier2\brcm\libraries\lib\20737(20736)

                            2. Edit makefile (APP_PATCHES_AND_LIBS += debug_hciulp_HandleCreateLLConection.a)

                            3. Clean build

                            4. Feedback the client message once timeout.

                            One of the below messages should be sent out if the LL connection be rejected.

                            log("\r command disallowed :\n");

                            ||
                            log("\r invalid hci command parameters:\n");

                            ||

                            log("\r acl connection already exists:\n");

                              I do not see the exact error message you mentioned, but only see _hciulp_HandleCreateLLConection and then see ConnTimer stopped: 2

                               

                              Is it correct?

                                Hi chihL_61

                                 

                                I would appreciate your input.  I followed your suggestion and did not see any error message that you mentioned.  Is it possible that I missed some steps?   Thank you.

                                  Below was the hci event detail show by your log, i am trying to figure out the cause. Could you help me to do more tests and check the event(connection complete event), are they the same?
