The problem is, that WiFi is not much reliable / secure and not always available.

ESP controllers are just perfect for controlling sensors and 'black boxing' telemetry by offloading this task form 'big brothers' like routers, linux boxes, etc - they start within couple of seconds and have minimal power consumption. I'm trying to build a standalone autonomous system with redundancy, environment monitoring etc, based on ready-made firmwares like Tasmota, Espruino, ESPEasy, or whatever else. Which obviously does not have sensor drivers, but will make esp a sort-of modem device.įirst of all I'm not talking about Smart Home usage patterns. This reminds me of the original ESP8266 AT firmware -> Maybe OT: Since you do mention raw protocol communication. What is the specific purpose of the linux board? Automation? On the program side of this, I'd imagine yhis would require to change debug + terminal to use some structured data protocol instead of just using new-line delimited strings. Is there any way to provide the ESP Espurna board with TCP/IP over serial, like PPP over serial client or something like this? The built-in WiFi can still be used as a service mode for initial configuration or “if everything goes bad”. For example, most of the commands do have error / ok message at the end, but were not specifically made for scripting purpose.

There is a terminal interface -, but it is closely tied up with debug printing and is mostly intended to be used with user present. If not, then is it possible to control / get status of the ESPurna board attached devices from the serial console commands to use in scripts from a linux board?
