Hi,

I am using the DT80M for a weather station and I don't want to use the in-built modem.

How to turn the modem off permanently ?

Because it keeps trying to connect, it sends these ghost strings - "SESSION FAILED - sim problem, will retry" error messages and throws off the server that I run downstream.

Kindly let me know how to disable the modem ?

Hi chintanp,

As default, the modem will switch on during any session activity or retries, to disable the modem completely you need to make sure three important components are fulfilled:

1. in DT profile setting modem timing control should be OFF, you can set this profile using PROFILE MODEM_SESSION TIMING_CONTROL=OFF

2. there is no session left in the session queue that related to the modem
   Check the queue using SESSION LIST and clear it using SESSION CLEAR

3. make sure you use Ethernet as an option for any data transmission, the default of data transmission in M type logger is internal modem.
   Example: COPYD dest=ftp://username:password@host-ip:port/pathname?priority=normal&interface=ethernet

*If you can't enable Ethernet option, try to use question mark (?) instead of ampersand (&) ?interface=ethernet

Best regards,
