Unused RX/TX

PostPosted: Sat Dec 20, 2014 12:47 am

After I'm done programming the ESP8266 and I want to run it without the FTDI in the final project:
1. What should I do with the RX and TX pins of the ESP?
2. Does the ESP check to see if there's a device on its RX/TX?
3. Is there a way to disable RX/TX on ESP via lua (to save power? and prevent stray inputs?)?
Thank you in advance.

1. best is to leave it unconnected
2. it depends on your running program.
and looking at your post, no it doesnt
care.
3. it wont save power disabling uart.
stray signal isnt uart pin issue either.

what i normally do to uart pins used for loading fw, is add connector for easy access. so in a long run that you will need to do fw upgrade (even if OTA upgrade is ebabled), it will be easy.
