Send SMS example not working

Open Mrfixit44 opened this issue 10 years ago • 2 comments

Hello, I'm new to this, I have a v2 of the GPRS shield. The Shield works with the serial example on the Wiki page so the board works and so does the SIM card. I installed the library. open up the Send SMS example, and change the number. This is where things get a little weird. I upload the sketch, with the modem off power up then turn on the modem and wait for the green light to blink once every 3 seconds. Then open the Arduino serial monitor and get the message

init error

If I power off the modem with the Arduino serial monitor still open it will say

gprs init success start to send message..

and nothing happens.

suggestions? Thanks, J

Generally message sending should wait for network being registered.
