Part Number: CC2642R

Hi,

I am using simpleperipheral example of  sdk simplelink_cc26x2_sdk_2_30_00_34.  I am able to make single connection properly with ble device. As per my use case i made 2 connection with cc2642r with different mobile phones. After 12 hours one device got disconnected and when i tried to make the connection again, 2nd device getting disconnected everytime with error code 0x28.

I am not able to make the connection after long run time. Can anyone please tell me why i am getting this error and how to solve this error?

    Hello,

    One of the potential causes of the status 0x28 is that the instant defined by a control procedure has passed, and thus there is an error in the control procedure. This is usually consistent with a control procedure issue. Do you have a sniffer capture of this failure?

    Additionally can you provide the following information:


    - What toolchain are you using?
    - What phone is it that is causing the issues?
    - How/where are you receiving the 0x28 status in your application?
    - Is this reproducible with a TI sample app or have you made changes?


    Thanks!
