MicroPython Errors on ESP8266 but not Pico board

[sharp wolf]

I narrowed it down to the timer or the call back blink but not sure what is going on.

from machine import Pin, Timer
from time import sleep
import machine

led = Pin(2, Pin.OUT)
timer = Timer()
toggle=True
led.off()

def blink(timer):
    led.toggle()

timer.init(freq=2.5, mode=Timer.PERIODIC, callback=blink)

MPY: soft reboot
Traceback (most recent call last):
File "<stdin>", line 6, in <module>
TypeError: function takes 1 positional arguments but 0 were given

Only getting this error for the ESP8266 aka NodeMcu Esp-12F board.

No issues on Pico for Pin('LED', Pin.OUT)

The LED on ESP comes on and stays on and then give argument error.

Please advise.
Thanks

Find the function that takes a positional argument that you didn't provide

Thanks, but this has not error on raspberry pico and works perfectly.
Only esp8266

They very likely have different machine libraries or the machine libraries are different versions

Hmmm, Thanks I will check.
