- Mon Nov 30, 2020 5:00 pm #89649 there must be something wrong in init.lua

somewhere you can read

Code: Select all...attempt to call field 'alarm'. (a nil value ...

followed by some stack trace
that could be the reason of all the garbage on the serial interface

remove that file and try this, it's a trivial led blink every 5 secs

Code: Select all-- init.lua
led_on = false
gpio.mode(4, gpio.OUTPUT)
gpio.write(4, gpio.HIGH)

periodic_task = function()
    if (led_on) then
        -- turn off the led
        print("led off")
        gpio.write(4, gpio.HIGH)
        led_on = false
    else
        -- turn on the led
        print("led on")
        gpio.write(4, gpio.LOW)
        led_on = true
    end
    tmr.create():alarm(5000, tmr.ALARM_SINGLE, periodic_task)
end

print("now running the application")
tmr.create():alarm(5000, tmr.ALARM_SINGLE, periodic_task)

i have tried the file but i got what you can see in attach.. i have also tried to modify the character from 8N1 to 7E1 in each speed ..... nothing !!
I've done so many tests that I don't know what I've done anymore....
now i'll start again ...

erase flash with flash_download_tool
load default files
load your files
with lua loader i'll put in your blink init, a call to version.lua

that's all you need

Code: Select allload your files

please don't

rename version.lua into init.lua
upload it and check that nodemcu 3.0.0 is running

then

create a new init.lua with just my blink example
and upload it
check what happens
