Compiler/CC2640: cc2640 ble device is not getting detected in BLE device monitor for OAD programming

Part Number: CC2640

Tool/software: TI C/C++ Compiler

Hello guys,

Im working on cc2640 , using ble sdk 2.2.1 .

My device is getting detected in mobile app, and able to perform OAD using the custom App.

But in the BLE device monitor, my device is not getting detected( not seen in the "BLE Network"). But I can see the device in "Event Log" in BLE device monitor as shown in the screenshot below.

If I change the advertisement packet with parameter GAP_ADTYPE_LOCAL_NAME_COMPLETE instead of GAP_ADTYPE_MANUFACTURER_SPECIFIC, device is getting detected. 

Please let me know what makes the difference in using these parameters, or some other GAP parameters are causing this issue?

Thanks in advance.
