Do not drive this signal high or apply a pull up resistor. When the nRESET_REQUEST signal is detected by the OptConnect ema™ Management MCU, it will attempt to properly reset the modem with a controlled shutdown. If that fails it will unconditionally shutdown the modem. -
Page 20: Firmware Updates Over The Air (Fota)
OptConnect ema™ Management MCU using microFOTA. When a FOTA update is triggered, the modem will output FOTA specific URC’s over the OptConnect ema™ Management UART interface to notify the host system that FOTA is in progress. When a FOTA update is in progress the host system must keep the modem powered and connected until the process is complete. -
