Hi I am just getting started with Zerynth, having the problem below when I attempt to upload the 'hello world' script. My NodeMCU is continually flashing a blue light also. 

[info] Got header: 33540000200000a794000b00000a026a
[error] No answer to probe

  • Hi robmarkcole,

    The header you got seems like you have not virtualized the device; try to create and virtualize the device following the steps as shown in the guide.

    Let me know if this can solve your issue.
