Can't send SMS after some time

[Vidmas30]

Hi everybody,

We have UniStream controller running application and modem for sending SMS alarm messages. Each alarm has it's own bit, that enables SMS send routine (from example library with operator string, now we have 3 operator's phone numbers). Now after some time we noticed that sometimes messages are not sent. Seems like there is problem when several alarms occur at same time. Maybe someone has suggestion how we could sort this issue? Thank you.

Maybe I expressed myself wrong - I mean I used SMS send routine from given UNIlogic example and used it several times for different alarm state. Maybe I've done it wrong and when several occure at the same time, not all messages are sent. Maybe there is some example where is shown how several messages are sent right way?

I think you should wait until one message is sent until you try to send the next one.
