Hey! I`m working with SIM800C modem and STM32 MCU. But the question about the modem itself. In general my program works fine, but my modem can suddenly restart in random moment - 5 minutes or 10 hours. I powered it with MP1584EN chip with 4v, added ceramic 1uF, tantalum 100uF and electrolytic 470…

SIM800C restarts from time to time

Remember these modem modules NEED up to 2A while negoriating or transmitting.
