Part Number: CC2340R5


Hi,

I am using the CC2340R5 basic ble peripheral code. We are currently experiencing where peripheral device is advertising and in Mobile default Bluetooth (No any Mobile application) trying to connect the peripheral device with passkey after successful connection in Mobile its showing as saved and can't able to connect again, need to remove the device info in Mobile Bluetooth settings to connect again (Tried with Multiple Android Mobiles). I have tried with unmodified basic ble peripheral example and the same issue is occurring .But in iPhone where peripheral device is advertising and in Mobile default Bluetooth trying to connect the peripheral device with passkey after successful connected. After disconnection when trying to connect to peripheral device its connecting again. But in android after pairing its just showing saved.

May I known why its happening and Please check and suggest the workaround.

SDK: simplelink_lowpower_f3_sdk_7_20_00_35.

Thank you.

    Hello Vignesh,

    Thank you for reaching out.

    I am working on reproducing the issue you are facing.

    Please help me with the following questions to better understand it and find the steps you are following to reproduce it.

    1. After a successful ble connection between the cc23xx and the device running android, the cc23xx device appears in the section of "Paired devices" (see attached image where its name is "AdvTest"). Whenever I deactivate and active bluetooth, the device pops up again in "Paired devices". Is this the state you are referring to as "device saved"?                                                                                                                                                                                                      
    2. Have you tried using the SimpleLink Connect app for android to see if this issue also happens there?
    3. Could you please share with me a screenshot of connection established using the iphone?

    Best regards,

    David.
