You can have a look on the following pages to see if there is a gateway in your vicinity:
Yes, but the device can only activate for one application at the same time. The keys you use here determine the application it will work with. To switch application you need to switch keys.
Yes, if you know what you're doing, you can run a private deployment of our open source routing services. Check out our Github to read how. We recommend most people to just use the public community network, as this will save you a lot of time and allows you to build awesome applications instead.
A real gateway is able to listen on multiple (at least 8) channels and all spreading factors at the same time. Single-channel gateways are fixed to one channel and spreading factor, so they will only receive about 2% of the messages unless you specifically configure your nodes to send at the exact same configuration as your single-channel gateway.
As LoRaWAN is a spread-spectrum radio protocol, single-channel gateways are not LoRaWAN-compatible. They can only be used for plain LoRa (without WAN) communication or for testing, and are not supported by The Things Network.
A "successful transmission" just means that the node transmitted the message. It does not mean that it was also received by a gateway. If you don't see the message in
ttnctl, in the Console or in your application, your node might just be out of range of a gateway.
In LoRaWAN we only send "join accepted" messages. If a join is not accepted, no message will be sent back to the node. A "denied" can therefore be caused by a number of other reasons than the server denying the join. First make sure that you're in range of a gateway. 9 out of 10 times this is the reason for joins not being accepted. If you're sure that you're within gateway range, you should check if the settings (AppEUI, DevEUI and AppKey) match the ones in the backend and check if they are entered in the right format (msb, lsb, hex).
When messages from your ABP device stop arriving in the backend, your device probably restarted. When this happens, your device typically resets the frame counters to 0 and starts sending again. The backend however will flag these messages as a possible replay attack, and will drop them. This behaviour can be disabled by disabling the frame counter check in your device's settings. This will make your device vulnerable to replay attacks, which is why we recommend to avoid ABP and prefer OTAA.
v2 or "Production" is the only supported version of the backend.
v1-staging have been discontinued.
