Does AT^SBC on Cinterion modules work with custom chargers?


Hello, I use a Siemens/Cinterion MC55 in my application. Since I can't use the integrated battery charging manager, I have to use an external one. The battery (Li-Ion) is still connected directly to the BATT pins. I suppose I need a 10K dummy resistor at BATT_TEMP to tell the module the battery is there. Will the AT^SBC command work in this situation? How does it calculate the remaining battery capacity? Is it just based on the voltage or does it need to know when and how the battery has been charged? - Thanks, Obi
