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
