CC2650: BLE Device Monitor Tool with CC2540 USB Dongle

Friends and Family,

From our customer:

----

Greetings!! 

We need support in resolving the issue that we are facing with “BLE Device Monitor Tool”.  We are using this tool along with the CC2540 USB dongle to test our end BLE sensor device which is integrated with CC2650MODA module.

 

USB dongle is flashed with TI’s “CC2540_USBdongle_HostTestRelease_All” hex files. Once we scan and try to connect our end sensor device on BLE device monitor tool, we are observing following error multiple times before we succeed in connection (shown in image also).

 

  • Connection time out
  • GAP Link Established: status =49 h=0000

 

Tool is not connecting with our end device at one shot. We have to keep trying multiple times until we succeed in connection. Could you please get support in this and help us why we are facing this issue.

 

Note that we have tried changing the GAP settings and scan time settings. Though the number of connection attempt reduced after slow GAP setting, but could not succeed in single shot connection every time we attempt to test.

 

                                                                                                                                                                                          

 

 

 

 

 

 

 

 

 

 

 

 

We know that BTool is an alternative solution for this test. However we found that it can scan only 5 surrounding devices at a time. If this has option to increase the device count number, we could try using this tool instead of BLE device monitor tool.

 

We are expecting your solution if possible.

Appreciate any input.

TY,

CY

    If you use BTool to connect to the CC2650MA sensor node, does it work fine?

    Hi Chris,

    If you want to test with BTool, you can set the number of devices that can be found by re-initializing your device. To do this, select the Adv. Commands section of BTool and send the GAP_DeviceInit command and set the maxScanResponses to your desired number. You cannot set it too high because of the RAM required to report back the devices that were found, but it can be set higher than 5.
