Delivery confirmation E220

[Yousefff1]

Hi @KrisKasprzak,

Is there any way that E220 would know if the transmitted message was delivered? I've been doing some research on this and it seems there is not.

I am currently using a very crude way to ensure delivery:

• Transmitter sends a message, and listens for a reply, entering a while with a loop, it keeps sending the data every 20 seconds and listening.
• Receiver receives the message and sends the confirmation.
• Once the sender gets the confirmation it breaks the while statement and goes to sleep.

Thank you so much for your help!!

You logic is about the only way to know if a message was received.

There is no way to know automatically. Doing this manually would require sending a confirmation back after receiving a message. This is not technically difficult, on the transmitter side, once a message is sent, start listening for a reply. You should add some type of timer to keep the listen from waiting forever.
