PLS62W-T Locking | Telit Cinterion IoT Developer Community

February 12, 2024 - 8:03am, 72 views

I am using the PLS62T-W USB product.
The application I wrote in Java language runs in 4G-RS232 bridge mode.
At some points where the GSM connection is bad, the connection with the device is sometimes lost. Breaks can sometimes last 1 hour, sometimes 10 hours, sometimes 2 days.

Note: The Java application we wrote includes HeartBeat (ping control), network control and then restarting, but I realized that it did not work.

We sent the following queries via USB when the modem was locked, but the modem gives the reactions we saw for the first time.
For example:
- For the first time, the modem ERROR response was returned to the SJAM command.
- It could not respond to many of our commands.
- In this case, our JAVA application does not work.
-AT^SCFG? The command response was incomplete.
- We sent the AT+CFUN=1,1 command, but the modem did not restart.

Can I get your comments about this situation?
