Reactor modem problem

[Frank68]

1. Check that the modem is detected when the system starts in System config > Status > System log.

2. Run this script and post what you get in Logs:

Code:

12345678910111213141516171819202122232425262728293031323334353637383940414243444546474849505152535455565758596061626364656667686970717273747576777879

tty1 = '/dev/ttyACM3' tty2 = '/dev/ttyUSB2' if io.exists(tty1) then   tty = tty1 elseif io.exists(tty2) then   tty = tty2 else   log('port not found')   return end port = require('serial').open(tty) if not port then   log('cannot open port')   return end function readstatus()   local data, res, simok, network   port:flush()   port:write('AT+CSQ\r\n')   data = port:read(1000, 1)   if data then     res = data:match('+CSQ: (%d+)')     res = tonumber(res)     if res then       log('Signal: ' .. tostring(res))     else       log('Signal: no response')     end   else     log('Signal: no data from port')   end   port:flush()   port:write('AT+CPIN?\r\n')   data = port:read(1000, 1) or ''   if data:find('CME ERROR') then     log('SIM: not found')   elseif data:find('+CPIN: READY') then     log('SIM: OK')     simok = true   else     log('SIM: unknown')   end   port:flush()   port:write('AT+COPS?\r\n')   data = port:read(1000, 1)   if data then     res = data:match('+COPS: %d+,%d+,"(.*)",%d+')     if res then       log('Network: ' .. tostring(res))       network = res     else       log('Network: no info')     end   else     log('Network: no data from port')   end   return simok and network end for i = 1, 20 do   if readstatus() then     break   end end

OK in the log i see error network no info and SIM not found signal 13, but in the phone the SIM works.

Why ?
