Hi,

Thank for the quick reply.
Here it goes.

[admin]

What LM hardware model are you using?

[andrepneves@gmail.com]

LM5p2-RIO3LTE

LM5M3CV15xA23010267

Do you have 3G/4G connection enabled? If it's disabled then the on-board modem won't be initialized.

It was disabled. When we try to enable it the LM stops responding.

This most likely caused by LM using mobile connection gateway instead of Ethernet.
Follow this guide if you only need SMS without 3G/4G: https://forum.logicmachine.net/showthrea...7#pid33127

It worked. Thanks!

I still have a strange situation. In the alert I still get "SMS handler lost connection" but the SMS are getting through. I only happens with a card from one provider. Using a card from a different provider it doesn't happen.

Modify AT:run() function in the user library as follows and post what you get in LM Logs tab.

Code:

12345678910111213141516171819202122232425262728293031323334353637383940414243

function AT:run()   local res, err, cmd, pos, sms   res, err = self:read()   if err then     if err ~= 'timeout' then       log('run error', err)     end     return err == 'timeout'   end   -- check for incoming command   if res:sub(1, 1) ~= '+' then     return true   end   pos = res:find(':', 1, true)   if not pos then     return true   end   -- get command type   cmd = res:sub(2, pos - 1)   -- check only for incoming sms   if cmd ~= 'CMTI' then     log('run cmd', cmd)     return   end   -- read from sim   sms = self:incsms(res)   -- sms seems to be valid, pass to handler if specified   if sms and self.smshandler then     self.smshandler(sms)   end   return true end

Here goes the log.

Change the same function as follows and see if it helps.

Code:

1234567891011121314151617181920212223242526272829303132333435

function AT:run()   local res, err, cmd, pos, sms   res, err = self:read()   if err then     return err == 'timeout'   end   -- check for incoming command   if res:sub(1, 1) ~= '+' then     return true   end   pos = res:find(':', 1, true)   if not pos then     return true   end   -- get command type   cmd = res:sub(2, pos - 1)   -- check only for incoming sms   if cmd == 'CMTI' then     -- read from sim     sms = self:incsms(res)     -- sms seems to be valid, pass to handler if specified     if sms and self.smshandler then       self.smshandler(sms)     end   end   return true end
