“HUZZAH ESP8266 breakout comes pre-programmed with NodeMCU's Lua interpreter. (NodeMCU 0.9.5 build 20150318 powered by Lua 5.1.4 ).
I have re- flashed the board with the latest micropython firmware ( ver1.9 )
The upython interpreter runs on the ESP8266 and I can type in commands and read out the results over serial. A serial console cable has been used to connect the board with one Raspberry Pi3 USB
port. Using the serial console program " screen "
I have started a REPL session.
The same operation can be done, previous Huzzah webrepl enabling and configuration, with WebREPL with the difference that the board do not need to be connected by a serial console cable but can be powered independently and connected bi Wi-Fi.
All the trials give positive results.”
