    Is this issue solved?

    I also have similar problem.

    Situations are below;

    1. Using two CC2530EMs on CC2530EBs.

    2.EBs are connected to PC via RS232C.

    3.Run 'SerialApp' on CC2530EMs.(Coordinator and Router)

    4.Connection with ZigBee was OK.

    5. On PC, I run two 'Hyperterminal' for COM1(to Coordinator EB) and COM4(Router EB).

    6. I typed some words on one Hyperterminal, then on another Hyperterminal there were the words I typed.

    7. I transfered a file via Hyperterminal, BUT transfering was stopped during sending. After that the connection failed.

     

    From 1 to 6, they are OK. But in situation-7, SerialApp seems to stop.

    Are there some solutions?  Please help.

    Hi,

     

    There is a known issue regarding the serialApp sample application:

    Quoting the ZStack-CC2530 Release Notes (known issues section)

     - SerialApp is not reliable when used for high-speed, large file transfers -

       the receiving application occasionally drops a byte.

    Hi, Igor.

    You're right. I found the quote in the Release Note.

    I appreciate your answer. Thank you so much.
