OSerror with rgbled

[johnmcdnz]

setup:
Pycom Lopy1
f/w: 1.18.2
atom+pymakr

I have a main.py of:

main.py -- put your code here!

import time

time.sleep(2)

print('main MAC1')

import pycom
print('LED test')
print (0xffffff)
pycom.rgbled(0x0)

Using atom I can run this file from the Run command, but it fails when synced with an OSError. It is also ok entering the code at the command line. The error is occurring on the rgbled code. If I # comment the line the following code does not error.

This is the complete trace from run or press of the lopy reset button:

OSError: the requested operation is not possible

Type "help()" for more information.

Note, this sample is from a larger code sample and I've taken back to the minimum lines that create the error.
I've reflashed the lopy successfully to latest code.

Any ideas?

@johnmcdnz you need to explicitly turn the heartbeat off before you can set a colour on the LED.

[sarthak04]

import time

time.sleep(2)
import pycom

pycom.heartbeat(False)

print('main MAC1')

print('LED test')
print (0xffffff)
pycom.rgbled(0x0)

Try this code. This should run perfectly fine.
