I suspect that they can Open up the WiFi part, because they own the IP through and through, being a carry over from their prior tech. (If so, please, please, please consider it. It unlocks all sorts of things on the WiFi side of this device.)
So how exactly does GNU make know where to grab the esp_wifi_* API calls then? That code must be on the system somewhere perhaps in binary? Can someone point out the part of the make process that handles this? Just our of curiousity. Thanks!
