(0)  Hi I am trying to use the CE-X25 library in order to send SMS through a MC35i Terminal GSM modem. However, I am having trouble using it, especially during the "init" stage (which produces error 4999) and the send stage (which doesn't even start). Has anyone used this particular modem successfully with the CE-X25 library? Is the library available for download (http://support.automation.siemens.com/WW/view/en/40616248) compatible with MC35i? If there are chances that this library works with the TC35i, then maybe there is some hope for the MC35i. Anyone has some info I'll be glad to know. Thanks in advance

(0)  Hello Aristo, it must work with your modem. 4999 can sometimes come because the modems do have different behaviors regarding the time between getting PIN and giving OK on this. Some modems (e.g. md720-3 will give you immediately the OK when the PIN is valid). Some modems (e.g. TC65 will give you OK not before logging into providers network) and further more consider about the signal quality and the signal strength which can delay the process. the application was build primary for md720-3. means with other modems (especially the TC/MC-series) the library-given timeout is too short --> 4999. But the next time you trigger init-routine it must be good! If it is NOT OK neither, then lets go into detail because it must be something different which causes the error...
