telit modem bugs
Hi,
There are many GSM/GPRS modems that use depending on your requirements...
You can control them from PIC or some other uC via AT commands via any UART port and/or directly via serial interface (Wavecom & Telit modules only)...
Now you must choose depending on following:
Most popular GSM modems manufacturers are: Wavecom, Telit, Siemens, SIMCOM & Sagem... There are others bu I have used only these...
1) Price : SIMCOM is cheapest but there are is a myth they don't work good (bugs, bad series etc..) ... However I'm satisfied from them. the only problem or me was delivery...
2) Features: Wavecom and Telit provide you option to include your program INTO their modules!!! Siemens has some good advantages as build-in Java VM. Sagem modules are very low scale and power consumption...
3) Package ... Some modules are provided with BGA package and in that way you can reduce budget for expensive modem connector !!!
Manufacturer: Price Control
SIMCOM very low external (AT)
Siemens expensive external (AT)
Wavecom expensive Internal (build your program INTO gsm module) or external (AT)... Programming with C++ (Open AT Suite)
Telit expensive Internal (build your program INTO gsm module) or external (AT), nice modules with integrated SIM card holder, GPS etc. (programming Perl)
expensive
Sagem - low price external (AT), very low power and scale factor...
All of these modules you can use and sell in EU without any problems ... They all have such certificates, so that isn'ta problem...
So, you must check in details their specification and features and to choose optimal module for your application...
If you give us some more details about your project we can advise you better
