- Mon May 25, 2015 3:12 pm #18440 Is there a way to output binary with NodeMCU. Its much easier to read binary on the Arduino than parsing strings back to ints.
I've tried Print("\0") but it seems a null characters just breaks the string. uart.write also takes a string as a parameter.
Is this possible?

i am not sure from looking at the nodemcu code put writing single chars as numbers not strings may do the trick.
But nevertheless i suggest just exchanging hex encoded data and use cr and lf for resync.
Makes some debugging via terminal possible.
