Hi all.
For years. I get the PMs related SIMCOM series.
So i want to give some tip for success.
Most important for you!
1. Make sure your power supply is most suitable for SIMx. (2,5 - 3 A)
2. After power cycle the modem, please don't send anything until you get "Call Ready" or "GPS Ready". THIS IS SO IMPORTANT.
3. Be aware of your modem is powered on or off.
4. Everytime wait for modem response.
5. For GPRS application; always use AT+CIFSR in init stage. Your network attachment not works otherwise.
6. When you develop, everytime use UART spy cable and PC terminal. This is Very very useful.!
