Re: Using the tx/rx pins not for UART
Thanks Deshipu, Hardware mod is a temporary band-aid fix. Uart is a prime communication interface for many applications requiring reliable functionality. I don't know what complexities are involved in finalizing Uart functionality in firmware and hopefully to include an option to turn uart Repl off ...

Re: Power supply control
Some of those relay modules use PNP transistors that need switching down from supply voltage, in which case GPIO high state (relay OFF) must be at supply voltage (5v).
NPN should be OK.

Re: Re-import module?
Thanks Dave,
pyboard 1.1 , firmware 1.8.2
Deleted some other code that was running in main.py at startup.
Hard Reset.
Good now .
Will investigate why it upset the importing of modules
Regards
John

Re: Re-import module?
Newbie question. AttributeError: 'module' object has no attribute On pyboard. From Repl trying to import and execute a very simple function. Very simple file A.py , saved in main root directory. def f(): print("test") import A, works OK. from A import f, does not work ImportError: cannot import name...

Re: Can anyone tell how to put .py file into the 8266?
Confirming that Webrepl file transfer works as per pfalcon link earlier.
This is now very easy.
Thank you all.

Re: Can anyone tell how to put .py file into the 8266?
I still can't see clear instructions (for newbies) on how to upload files to ESP8266. Brief link in FAQ points to documentation that states. so give it a try using webrepl_cli.py from the repository above :? For a newbie that is not familiar with a Linux OS command line and probably does not even us...

In the meantime this configurable software UART works in the Arduino environment.

Re: ESP8266 is great (with ideas for improvement)
Since ESP has only 1 full/bidirectional hardware UART (Second only supports Tx, Rx(Gpio8) is tied to external Flash) which severely limits direct UART interfacing.
Are there any plans to expand number of Uarts in Micropython through bit bang firmware implementation?

John

Re: Direct communication between ESP8266 nodes
ESP8266 Mesh Users Guide . I'm sure Micropython crew know and have a much better idea about this. http://www.signal.com.tr/pdf/cat/30a-esp8266_mesh_user_guide_en_v1.2.pdf Implementation of Mesh network similar to Fig 1.4 would be nice. Once again without being disrespectful, as a backer of the kicks...
