reactor not get ip from GSM

[Frank68]

Greetings

I changed the SIM and mounted a tested working one on a phone, my problem is that it does not receive IP from the cellular network, even if the signal is there.
Latest firmware version available
What can it be?

Thank you

Check that you have correct APN and dial number settings.
Post what you have in System config > Status > System log.

APN is correct

need the dial number of SIM ?

thank's

[admin]

Default dial number is *99***1# but it might be different, check with your operator.

Also post what you have in System config > Status > System log.

the dial number be set in 3G/4G/ ppp connection or in resident sms script?

in system log see

May 23 08:04:52 LM5R_VERGATO daemon.err pppd[1932]: Connect script failed

Dial number is set in System config > Network. But you don't need to specify it if the default one is used.

Is SMS script working for you?

Yes I use only one number

the error il log why? error ppp connection, not have ip from mobile network.

If SMS script is working then the hardware is ok. This means that your configuration is wrong. Maybe a username or password is needed. Your operator should provide all settings - APN, user/password (if applicable) and dial-up number.

I use same SIM OPERATOR on other LM REACTOR and the same config working good , this no ?

[admin]

Have you tried using this SIM on a different LM?

[Frank68]

Have you tried using this SIM on a different LM?

Now I have put new SIM tested on other LM and the new SIM working on ther LM.

now I have ip from network but have this problem in log

It's not a user script, it's an init sequence of the 3g/4g services. Usually this error means that the configuration is incorrect.

If you are sure that all settings are correct then the only option is to replace the SIM card.

I check the sim on phone and work correctly

the IP is provided from mobile netwok but have this error.

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)

Keep the dial number default (dial = '*99***1#') and try again. This number is never your SIM number.
