I was curious if there is a way to connect the ESP8266 NodeMCU over LAN without a WiFi connection using a router. I could find little to no documentation on this, so any libraries that could be used would be helpful.

If not, I'll describe my situation. I might have limited/no access to WiFi at an activity I'm doing and only want to use the ESP8266 if I am able to program it wirelessly. Thus, I need ideas on how I can use this device with limited WiFi capabilities in order to wirelessly program it, otherwise I will switch the hardware I will use. So, another possibility could be a hotspot on a phone, but that is a bad option, both because the phone service might be very little and it would be charged. Another would be bluetooth, but I found nothing about bluetooth capabilities.

If anyone has any ideas as well I'll be open to suggestions.

Thanks.

The unofficial answer: there are people trying to get LAN-support going using bit-banging, though it's all proof-of-concept.

Normally you program the ESP8266 over serial BTW (although OTA is possible if implemented).

The ESP8266 doesn't have BlueTooth, but it's bigger brother the ESP32 does.

Assumption is the mother of all f*ckups. At least: that's what I'm assuming.
