Base/Rover disconnect problems ...

We are having issues with frequent base/rover disconnects. The T3 base is on a fixed pole connected to a Jetpack & is located 650' from a Verizon tower. The LS+ rover has a Verizon sim card and is located a short distance (<10 miles) across town.

We don't know if it is the base or rover disconnecting from Verizon. I suspect it is the rover disconnecting. We don't get base disconnect warnings and the point collection continues as an autonomous position since it has no RTN base data stream.

Any thoughts on what is causing this? Could it be a loose sim card in the rover? Loose antenna?

I thought it could be connected to the "Base Displacement Guard" pop-up screens I posted about earlier. I think I have resolved that issue but the base/rover disconnect problem persists.

The sim card should not move if it is seated correctly. You should feel it catch when you insert it. To remove it you will need to lightly press down for it to release and pop up. I don't think the card is the problem. You can tap on the cell icon to see if it is connected and has internet access on the LS. Have you tried powering the cell modem on and off on the LS when this happens?

The main problem is we have no notice or warning of the disconnect. The rover point collection continues but there is no RTN data stream. We have to go back to the base/rover screen to see we are not connected. And we have to reconnect and start over.

The loss of connection will show on the LS without going back to the base. Tap the cell icon, on the right you should see connected. If it says socket failed then it isn't connected. If the cell icon on the LS shows internet access yes but socket failed then the issue is likely at the base. If the LS show no internet access or has an exclamation mark over the cell icon then you have no internet at the LS. If this is the case power cycle the cell modem and/or reboot. You should run a speed test to check the data upload and download speeds when you lose connection.

Also, the base/rover screen will not show as connected unless you are connected over bluetooth or wifi. So when you are 10 miles out and go into base rover it will not show anything on the right hand side. Is this what you are talking about when you say it is not connected?

Charles I know this is an old post. In case this isn't resolved, I had connection problems with the jet pack that were resolved when added the internal radio to the LS.
