Change to new default baudrate 115200
Posted: Sat Mar 12, 2016 5:43 amThis had me fooled for a while yesterday 
I'd just got a new Custom build from the Dev branch and hadn't realised that the NodeMCU team had finally got round to having a more sensible default baudrate. 9600 was so 1980's
I don't actually know of any reason not to run at 921600 - 1Mbit/s isn't that unusual in other serial devices. For NodeMCU boards with onboard USB<>RS232 chips the only unbalanced RS232 signal path is a few mm of PCB trace - and anyway, I use it all the time in ESPlorer even with a FTDI cable where the 921600 is rattling down a meter of multicore cable.
Note that the NodeMCU serial interface uses 115200bps at boot time.

You can easily change this higher if you do your own Docker build. 115200 is a trade-off: it is a lot better that 9600 and solid on all current USB-UART chipsets, but feel free to spin this up as high as your dev system will support.
