    Hi All,


    Sending multiple IDENTIFY messages to the SIM in quick succession only seems to return a response from the first message.

    for example, sending @2102 and @2104 after each other only returns the firmware version (02).
    If my code alternates, so sends one command then on the next time around send the next command, all is fine. This allows for checking the incoming serial data, so would there likely be a buffer full type issue going on here?



    Cheers,
    Paul

    Are you sure it's not actually replying? I can send @2102<CR>@2104<CR> and I get two responses... as a quick test I just used an internal tool (Devkit), so I'm not sure exactly what the time interval between the two is, but the second command gets sent before the first reply comes back.
