I have IoT system. The platform is Thingsboard and the MCU is STM32, and the communication unit is SIM5300e. It was working fine last week, now I cannot send or receive anything from MCU to the platform. The SIM5300e can establish GPRS connection and open/close gprs_http. However, the init_http() command is not stable, sometimes we get OK and sometimes not.
