Hello Everyone, First time poster.
I have recently begun work on my senior project which uses the SM5100B-D module available here http://www.sparkfun.com/products/9607 on sparkfun.
I have been playing around with it for a few weeks with no luck and i am beginning to get worried. This is the feedback i get from the module using the starter program…
+SIND: 1
+SIND: 10,“SM”,1,“FD”,1,“LD”,1,“MC”,1,“RC”,1,“ME”,1
+SIND: 3
+SIND: 8
+SIND: 4
I have an antenna attached but i still always get the SIND: 8 // no connecting to wireless network. The T-mobile Sim card works on my Phone fine.
I am afraid i may be doing something wrong when i attempt to set the cellular Band with the “AT+SBAND=7” at-command. The thing is, when i send this command i get NOTHING back from the module to indicate it received the command at all. Shouldnt i receive an “OK” return from the SM5100B?
