How can I retrieve IMEI number from a device running OpenWRT?
I've got a Chinese WiFi/Cellular router that came pre-loaded with OpenWRT (OpenWrt Barrier Breaker unknown / LuCI Trunk (svn-r10457)).
How can I retrieve the IMEI number for the 4G interface it has? (The interface appears to be named "3g-4G_WAN".)
Is there a command I can use when logged in via SSH, perhaps?
