We use EC25-E modules (firmware EC25EUXGAR08A17M1G_20.200.20.200) in 64-port modem pools, connected over UART. On some modules, always the same ones, the port stops responding after 30-40 minutes: no answer to AT commands and the SIM is no longer detected, until we power cycle the pool. Is this a known issue, and is there a firmware update that fixes it?
Hi @JSJSJSJSJ
