in my project i want to measure the battery voltage and i am using the (node.readvdd33()) command.
as you know , that command doesnt work in staion mode .
so what i did is to run that command before connecting to a WIFI and save the value in txt file.
and its working good.
after that i created a LUA file that print the value from the txt file:
file.open("value.txt", "r")
print(file.read('\r'))
file.close()
and when i press do file for the LUA file its pring the value.
but when i am trying to send the value to easyiot with that command:

elseif string.find(payload,"BStatus") then
print("Received BStatus request")
myval = nil
while myval == nil do
print("reading value")
myval = dofile("BStatus.lua")
end
print("read "..myval)
conn:send((myval))

it gives me

Input: BStatus
Received BStatus request
