I was looking for an Arduino library for the ESP-01 Wifi module, the ESP8266 based one that works using serial and AT commands. I could only find old ones which did not work with Pi Pico / latest ESP-01 firmware.
So I forked and hacked a working version. - https://github.com/Workshopshed/sam32wifiesp
Am I missing something or is there other libraries that are actively maintained?
Spotted lots of mention of "Wifi Managers" in the libraries, anyone know what the purpose of those is? Do they provide a WifiClient or some other functionality?
Also spotted there are MQTT commands built into the firmware - https://docs.espressif.com/projects/esp-at/en/release-v18.104.22.168_esp8266/AT_Command_Set/MQTT_AT_Commands.html which could make for more efficient coding rather than needing the pubsub library. Could be useful if you are short on memory.
