reactor not get ip from GSM

[admin]

Disable SMS script and 3g/4g connection then run this script once and post what you get in Logs. Don't forget to change apn variable value.

Code:

apn = 'PUT_YOUR_APN_HERE'
dial = '*99***1#'

io.writefile('/sys/class/gpio/export', 8)
io.writefile('/sys/class/gpio/export', 71)

io.writefile('/sys/class/gpio/gpio8/direction', 'high')
os.sleep(1)
io.writefile('/sys/class/gpio/gpio8/direction', 'low')

io.writefile('/sys/class/gpio/gpio71/direction', 'high')

tty1 = '/dev/ttyACM3'
tty2 = '/dev/ttyUSB2'

for i = 1, 20 do
  os.sleep(1)

  if io.exists(tty1) then
    tty = tty1
    break
  elseif io.exists(tty2) then
    tty = tty2
    break
  end
end

if not tty then
  log('init failed')
  return
end

buf = {}

function send(cmd, timeout)
  port:write(cmd .. '\r\n')
  local res, err = port:read(1000, timeout or 1)
  return res, err
end

function sendlog(cmd, timeout)
  local res = send(cmd, timeout)
  if res then
    buf[ #buf + 1 ] = res
  end
end

port = require('serial').open(tty)
log('open port', tty)

for i = 1, 20 do
  res = send('AT')
  if res then
    break
  end
end

if not res then
  log('no response')
  return
end

sendlog('AT&F', 10) -- reset settings
sendlog('ATE1') -- echo enabled
sendlog('AT+CGDCONT=1,"IP","' .. apn .. '"') -- set apn
sendlog('ATD' .. dial) -- connect

res = table.concat(buf)
log(res)
