Troubleshooting Open Data Sessions Without Data

What are some troubleshooting steps for open sessions without any data?

Symptoms:

• The device shows as connected in the Monogoto Hub, but no data is transmitted or received.

• The device may respond to network registration checks but fails to establish a working data session.

Verify:

• Your device is powered on and attempting to connect

• Your device has the APN set as data.mono

Troubleshot:

Once you’ve checked the above, here are the top troubleshooting steps using AT command access for this issue:

1. Monitor your SIM in the Monogoto hub to confirm data sessions within your events.

2. Troubleshoot your device using AT commands

   1. Check PDP Context: AT+CGACT? ➔ This will show if a PDP context is active.

   2. Check IP Address Assignment: AT+CGPADDR ➔ If the IP address is 0.0.0.0, the context is likely not properly established.

   3. Confirm APN Configuration - ensure the correct APN is set for Monogoto: AT+CGDCONT=1,"IP","data.mono" ➔ Misconfigured APN settings are a common cause

   4. Session Reset - manually reset the PDP context with: AT+CGACT=0,1 AT+CGACT=1,1

   5. Run a ping test: AT+PING="8.8.8.8"

3. Firewall and Routing Issues: Confirm that the device is authorized to communicate over the configured APN. Ensure firewall rules on the network are not blocking traffic.
