Indeed, that is the latest version of the firmware linked from The Things Store: https://connectedthings.store/gb/lorawan-gateways/outdoor-lorawan-gateways/the-things-outdoor-gateway-868-mhz.html
But I really don’t thing that is ACTUALLY the latest version of the Browan Gateway. I think it should be more like version 3.0, as seen in their documentation on their website: https://www.browan.com/product/outdoor-micro-gateway/detail. Have a look at the AWS IoT demo doc for instance.
Does anyone have any idea on how to get hold of latest firmware? I think that latest firmware should also have compatibility with Lora Basic Station.
Also, it would be very much appreciated if anyone would be able to advise on how to use TTOG with The Things Stack. See post here: TTOG & The Things Stack
