#175740 - talk serially to a GSM MODEM Responding to: ???'s previous message |

I wanted to try ... to talk serially to a small GSM MODEM module without relying on my PC. There are really two separate issues here: 1. Talk Serially That is platform-specific. On a microcontroller, you will probably have to deal with the low-level details of drving the UART; on a PC (or similar) the low-level detail is done for you, and it's "just" (sic) a matter of using the appropriate APIs. But, once you know how to "do" serial comms, it can be applied to any task you like - it's not specific to any particular peripheral (such as a GSM modem). There's a whole section in this site's FAQ about 8051 serial comms - including this "beginner's gude": http://www.8052.com/faqs/120308 2. Control a (GSM) Modem This is entirely platform-independent - it's "just" (sic) a matter of sending the appropriate AT commands, and interpreting the responses If you're already familiar with PC programming, it would probably make sense to start by doing it on a PC - then, once you've got the hang of it, move to a microcontroller... The 'Links' section of this site has links to the GSM specs - including the standard AT commands |
