Hello all,
i have one issue in sim808 module.
1) when i connect VBUS pin to the +4.1Vdc and connect battery to the VBAT pin sim808goes in power down mode when i disconnect it external battery.
2) When i connect VBUS pin from +5V dc continuous supply(charger) and connect battery to VBAT pin my sim808 restart continuously.
i have Li-Ion 3.7V dc battery.
3)and also tell me what would be the exercise if i dont want to connect battery. and sim808 works only on external power source(+4.1DC).
4) if there is no solution without connecting external battery please let me know how do i automatically get it in normal mode after power down mode when battery fully discharge and i connect it with external supply.
