FCM Data receiving event error

Legacy Open AT
1

Dear all,

I’ve created a program that:

  1. Subscribes to FCM on UART1, the “Opened” event is received.

  2. After the “Opened” event, a change to data mode is performed. The “Data mode” event is received

  3. After de “Data mode” event is received, the string “open” is sent using UART1. I can see the “open” word in hyperterminal.

  4. The problem:

    1. If a key is pressed in hyperterminal (except A key) the Data received event is not raised.
    2. If the first key pressed is the “A” or the “a”, the Data received event is raised and after that any key raises the event.

Why is this happening?
