Is there a easy way to send to multiple remote numbers?
I have a simple code that allows me to change the input to two relays and also have 4 high/low alarms. The code works and SMSs me when the high/low changes.
But I am looking for a easy way to add another phone number
Thank you
Dave
Sadly not, unless you subscribe to a service that supports SMS broadcast.
What I do, is create a FIFO queue of messages and pop them out as fast as the modem will allow.
You can get much higher speed if you use modem status messages rather than send + delay. (about 1 sec total per recipient).
