The Dragino LGT-92 LoRaWAN GPS tracker is a very cool Open Source device to do some experiments with LoRaWAN. I always wanted to have a real-life example for LoRaWAN to try out and see how good the coverage is in Switzerland, with this device I found it. It can be bought f.e. at bastelgarage.ch.
Getting the data out of the tracker needs some work though. By default the device connects to The Things Network (TTN) which is a network of gateways all around the world (I contribute to the network by sharing my LoRaWAN gateway).
While I'm a fan of LGT-92, it also has some drawbacks: It only reports latitude and longitude while I would also like f.e. accuracy or altitude data. Configuring the device over AT commands needs serial adapter and some fiddling until it works. Firmware upgrade is only possible via an ST-Link v2 adapter which I don't own (yet - bastelgarage.ch should have it in stock soon(ish)). My device currently runs version 1.4 of the firmware and I'm looking forward to upgrade it to 1.5 once I get the adapter.
