Hi every one,
my quation is how to connect multi sim card saying 3 of them to gsm modem like sim808 or other? my second quation how to implement firmware on arduino or other microcontroller?
sim5360 you needn't a external Mcu just this module.you can program it with LUA scripting language. and there is a bult-in GPS.

Lua application note:
**broken link removed**
why not re-design your product e.g using SIM5360 you can use it for communication and as substitut for microcontroller to reduce the cost, it accept LUA scripting and integrate peripheral(spi, i2c, gpio...). it cost 21 dollars.
im working on project (PIC16F1705) and i try to understand the Convesion library, i used an example provided in the exemple folder.

The RS-422 specification recommends twisted pair cable. I recommend erring on the safe side and using shielded cable. Shielded cable is only slightly more expensive than unshielded. It can be difficult to quantity whether shielding is required in a particular system or not, until problems arise.

HANDLING MODEL SIMULATION FAILURES
Subcircuit models vary greatly in complexity and design. As a result, some models are
easier to simulate than others. As a general rule, if PROSPICE could not simulate your
circuit with its...
check the buffer (RAM for received data) lan variable, maybe is fixed at 50. for sent data maybe you have fixed this variable2 to a value superior to 50 this is way you haven't problem in transmitting data.
