For the logger. Look at the SLF4j and SimplerLogger class. If you You are using your own logger then the best way might be just to add another interface to SLF4j and use the SimplerLogger as a template.
I dug up a couple of notes. The 172 170 156 160 models, and maybe others, are specified to use 500mA @ 5V at PEAK output in 3G modes. There heat dissipation is related to this out course and the hotter they are the less efficient they are. In other words don't stack them one on top of another if possible. If you want to try to minimize power usage you can use the commands above to force the modem to stay in GPRS mode, which is usually the most efficient. You will also want to look at the RSSI or S/N ratio and see your reception. If you have a low RSSI (10 maybe) or a low Signal / Noise ratio then the modem has to compensate using more power. Get the best signal you can by moving the modems. This is especially true if the modems are inside of a computer cabinet. Most of those act as RF shielding. Again don't stack them one on top of the other as this will increase noise and the shielding on one modem can actually act as interference for the next modem if close enough. -nxn On Jan 18, 7:08 am, Gon Argüello <[email protected]> wrote: > Hi! > Thanks a lot for your help and will! > First of all I must tell you that I´m not really familiar with low level > programming, serial communication or AT commands.
