Dear Sir.

I use these commands to connect the Modem ON and OFF.

I need to know  if the result of the these commands the Modem communicates with the Cell tower ?

Please Advide.

Hello Ephraim,

I need to know  if the result of the these commands the Modem communicates with the Cell tower ?

I’m not quite sure if I fully understand your question. But yes, lte_lc_normal() basically is a wrapper for AT+CFUN=1, setting the modem to normal operation mode. lte_lc_offline() however, will not result in search for a network, but send the modem to offline mode.

Regards,

Markus

Hi.

We are testing our custopm board which has printed antenna ,

current consumption during TX .

1. If in line of sight with the cell tower , current is 5 to 10 ma.

2. outdoor 40 to 60 ma.

3. Inside building 350 to 500 ma.

I know that the Modem and cell tower negotiate  to detrmeine the Modec tx power needed.

Which routine is responsible for it ?.

What realy happens with the command lte_lc_normal()  ?.

Does is communicate wit the Cell tower ?.

Thanks
