When I run the example script (6:39), I get stuck when trying to connect to LTE. It just says waiting for network… and switches to RAT and retrying NBIOT. This is the second sim I’ve tried (optus and vodafone) here in melbourne, Australia. Any help?

Hey @Arthur214942, welcome to the forums!

If the antenna is correctly plugged in, and you are getting this error, it is likely going to be with your SIM card. If you have one, we found Telstra SIMs to be the most error-free in Australia.

If you can test this would be very helpful, if not let us know and we can dive deeper.

Cheers!

I apologize if this is a daft question but, would the Walter with an LTE antenna and a GPS antenna paired with a SIM card provide reliable cellular service?

Also, would you be able to power the until with a battery to make it conveniently portable?

Hey there, @Tim316410, and welcome to the forum. Glad to have you here.

Yep, that’s the exact purpose of this board provided that you mean stuff like telemetry and tracking rather than phone-style data use. I’ve found Telstra to be the most reliable carrier for this board in Australia, but if you’re overseas its probably best to do so some research on who would be the best IoT provider for you.

I should also note that you’re not going to get 5G speeds. You’re going to getting speeds in the range of kbps, but should be plenty for most IoT operations.

And absolutely you can power it from a battery. You can either power it directly from the VIN and GND pin or via the USB port, which is certainly easier for wiring. I don’t have any data on how its power usage, so I wouldn’t want to guess at the battery life. You’d probably need to do some prototyping with different batteries to be certain.

Thank you, telstra worked like a charm
