Pico W not connecting

[cbrmichi]

Hi,
I´m using a pico W and stuck at connecting the board to the pico w. I just wanted to try the provided test-
files.
The pico is connected and powered by USB while the board is powered by battery (6v). The onboard LED is on.

Code:

import PicoRobotics
import utime

board = PicoRobotics.KitronikPicoRobotics()

I´m getting this error:

File "<stdin>", line 4, in <module>
 File "/lib/PicoRobotics.py", line 189, in __init__
 File "/lib/PicoRobotics.py", line 18, in initPCA
OSError: [Errno 5] EIO

So i tried i2c.scan(), which gave me [108, 112]. So it should be connected and working, but it doesn´t.
Could you please tell me, what is wrong?

Thanks in advance,
Michael

Hi @cbrmichi,

Hi! At first i tried using circuitPython. That did work, but i wanted to use microPython. The support (thanks again!) suggested reinstalling the newest microPython (w!) firmware. I did that before having tried circuitPython, but did it again next day and it worked immediately. From this on the problem was solved. Maybe changing between the Firmware helped... And don't forget to check the power switch on the board :) user-redans ***@***.***> schrieb am Mi., 7. Feb. 2024, 15:23:

Having the same problem, which version are you currently using ?

[jkozniewski]

Same here - tested with latest official build v1.22.2 and latest preview build v1.23.0-preview.343.ge60e8079a with no success, @KitronikLtd - is the board just incompatible with pico W ?
