Question
How to improve the 4G connection on a HMI Box module with a weak signal ?
Description
If you use a Magelis IPC (HMI Modular Box) with a weak 4G signal (like a 2G signal), is it possible to meet some connection interuption due to the weak signal.
After a signal interruption, a device mechanism waits 10 minutes before to try to connect the 4G interface again.
To come back again more faster is it possible to use the script as bellow to activate the APN again :
AT+CFUN=4 //Enter to airplane mode
Wait(5Seconds)
AT+CFUN=1 // Network mode
Wait(30Seconds)
AT+COPS?
AT+UPSD=0,1
AT+UPSD=0,1,\""+apn+"\"
AT+UPSDA=0,3
AT+UPSND=0,0
This script will reduce the waiting time from 10 to 1 minute
